 pidadr

    OpenVMS usage:process_id
    type:         longword (unsigned)
    access:       modify
    mechanism:    by reference
    Process identification (PID) of the process whose system service
    logging characteristics are to be modified. The pidadr argument
    is the address of the PID.

    Supported only for use with PPROP$C_SS_LOG_ENABLE, PPROP$C_
    SS_LOG_DISABLE, and PPROP$C_SS_LOG_UNLOAD. Otherwise, must be
    specified as 0.

 prcnam

    OpenVMS usage:process_name
    type:         character-coded text string
    access:       read only
    mechanism:    by descriptor-fixed-length string descriptor
    Process name of the process whose priority is to be changed. The
    prcnam argument is the address of a character string descriptor
    pointing to the process name. The process name can be 1 - 15
    characters long.

    You can use the prcnam argument only on behalf of processes
    in the same UIC group as the calling process. To affect system
    service logging for processes in other groups, you must specify
    the pidadr argument.

    Supported only for use with PPROP$C_SS_LOG_ENABLE, PPROP$C_
    SS_LOG_DISABLE, and PPROP$C_SS_LOG_UNLOAD. Otherwise, must be
    specified as 0.

 property

    OpenVMS usage:integer
    type:         longword (unsigned)
    access:       read only
    mechanism:    by value
    A constant that selects which property to set.

    Valid values for property are defined by the $PPROPDEF macro as
    follows:

    Property Code         Description

    PPROP$C_CASE_         The type of case lookup to use. This value
    LOOKUP_TEMP           is set for the life of the currently
                          active image. This value reverts to the
                          permanent case setting on image rundown.
                          In the absence of an explicit case lookup
                          specification in a user-provided NAML,
                          RMS uses this value to determine the case
                          setting for the current file operation.
                          Valid values are PPROP$K_CASE_BLIND and
                          PPROP$K_CASE_SENSITIVE.

                          For additional information, see the Guide
                          to OpenVMS File Applications.

    PPROP$C_CASE_         The type of case lookup to use. This value
    LOOKUP_PERM           is set for the life of the process or
                          until the case is set agairundown. Setting
                          this value affects only future activated
                          images for this process. To change the case
                          setting for the current active image, you
                          must modify the PPROP$C_CASE_LOOKUP_TEMP
                          setting.

                          Valid values are PPROP$K_CASE_BLIND and
                          PPROP$K_CASE_SENSITIVE.

                          For additional information, see the Guide
                          to OpenVMS File Applications.

    PPROP$C_SEARCH_       Processes the active search mode. The value
    SYMLINK_TEMP          reverts to the permanent setting on image
                          rundown. Valid values are PPROP$K_SEARCH_
                          SYMLINK_NONE, PPROP$K_SEARCH_SYMLINK_ALL,
                          and PROP$K_SEARCH_SYMLINK_NOELLIPS.

    PPROP$C_SEARCH_       Processes the permanent search mode. This
    SYMLINK_PERM          value is set for the life of the process.
                          Changing this setting only changes the
                          behavior of subsequently activated images.
                          Valid values are PPROP$K_SEARCH_SYMLINK_
                          NONE, PPROP$K_SEARCH_SYMLINK_ALL, and
                          PROP$K_SEARCH_SYMLINK_NOELLIPS.

    PPROP$C_DEADLOCK_     The per-process deadlock wait time (in
    WAIT                  100-ns units). A value of zero resets and
                          disables the per-process deadlock wait time
                          and fallback to the systemwide deadlock
                          wait time that comes from the system
                          parameter DEADLOCK_WAIT. Valid values are
                          in the range of 100000 (=10ms) and 10000000
                          (=1 s). If the value is too small, the per-
                          process deadlock wait is set to 10 ms; if
                          the value is too large, it is set to 1 s.

    PPROP$C_HOME_RAD      The Resource Affinity Domain (RAD) to which
                          the process is assigned. Newly mapped
                          memory in the process will come from the
                          home RAD of the process. Currently mapped
                          memory will not move into the new home RAD
                          unless $PURGWS is issued.

                          Valid values are integers between 0 and the
                          maximum RAD on the system. Valid home RADs
                          must also contain either memory or CPUs.

    PPROP$C_KERNEL_       Sets the process specific limit of the
    THREAD_LIMIT          number of kernel threads that can be
                          created. By default, this is controlled
                          systemwide through the SYSGEN parameter
                          MULTITHREAD. A value between 0 (use
                          default) and the current setting of the
                          MULTITHREAD parameter can be used.

    ENABLE

    PPROP$C_PARSE_        The type of command parsing to use. This
    STYLE_TEMP            value is set only for the life of the
                          image. The value reverts to the permanent
                          style on image rundown. Valid values
                          are PARSE_STYLE$C_TRADITIONAL and PARSE_
                          STYLE$C_EXTENDED.

    PPROP$C_PARSE_        The type of command parsing to use. This
    STYLE_PERM            value is set for the life of the process
                          unless the style is set again. Valid values
                          are PARSE_STYLE$C_TRADITIONAL and PARSE_
                          STYLE$C_EXTENDED.

    PPROP$C_SS_LOG_       Stop logging system service requests
    DISABLE               for the current or specified process. If
                          logging was previously disabled, the value
                          returned in prev_value is 0. If logging was
                          previously enabled, the value returned is
                          1.

                          For more information, see the HP OpenVMS
                          System Analysis Tools Manual.

    PPROP$C_SS_LOG_       Allocate log buffers and enable logging of
    ENABLE                system service requests for the current
                          or specified process. If logging was
                          previously disabled, the value returned in
                          prev_value is 0. If logging was previously
                          enabled, the value returned is 1.

                          For more information, see the HP OpenVMS
                          System Analysis Tools Manual.

    PPROP$C_SS_LOG_       Stop logging system service requests for
    UNLOAD                the current or specified process and close
                          the log file so that it can be analyzed. If
                          logging was previously disabled, the value
                          returned in prev_value is 0. If logging was
                          previously enabled, the value returned is
                          1.

                          System Analysis Tools Manual.

    PPROP$C_TOKEN         Controls the token size used by DCL. When
                          the bit is clear (the default), traditional
                          tokens are used, and each command token can
                          hold up to 255 characters. When the bit is
                          set, extended tokens are used; each command
                          token can be up to 4000 characters.

    PPROP$C_UNITS         Controls the process units. When the bit
                          is clear (the default), all size-related
                          numbers are displayed in blocks. When
                          the bit is set, size-related numbers are
                          converted to bytes.

 value

    OpenVMS usage:integer
    type:         quadword (unsigned)
    access:       read
    mechanism:    by value
    A quadword value to which to set the property.

 prev_value

    OpenVMS usage:access_mode
    type:         quadword (unsigned) address of a quadword value
    access:       write
    mechanism:    by reference
    The address of a quadword that will receive the previous value of
    the property.

 bufsize

    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       read only
    mechanism:    by value
    The requested system service log buffer size in bytes. Supported
    only for use with PPROP$C_SS_LOG_ENABLE. If omitted, it defaults
    to 65,024 bytes. The maximum value is 65,024 bytes. The minimum
    value is 4096 bytes.

 bufcnt

    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       read only
    mechanism:    by value
    The requested number of system service log buffers. Supported
    only for use with PPROP$C_SS_LOG_ENABLE. If omitted, it defaults
    to 2. The maximum number of buffers is 6.

 flags

    OpenVMS usage:mask_longword
    type:         longword (unsigned)
    access:       read only
    mechanism:    by value
    Flag mask specifying the enable logging request. The flags
    argument is a longword bit vector in which each bit corresponds
    to a flag. The $LOGTYPDEF macro and the LOGTYPDEF.H file define a
    symbolic name for each flag.

    The $LOGTYPDEF macro defines the following symbolic names for the
    fault characteristic codes:

    Symbol         Description

    LOGTYP$M_      Log system service arguments.
    ARGS
    LOGTYP$M_      Write log information to a file.
    FILE

    If you specify the flags argument as 0, the service defaults to
    logging to a file and logging arguments.

    If you specify LOGTYP$M_ARGS but lack privilege, service
    arguments are not logged.
