NAME

    pthread_attr_setstacksize - Changes the stacksize attribute of
 			       thread creation

 SYNOPSIS

     #include <pthread.h>

     int pthread_attr_setstacksize( pthread_attr_t *attr,
                                    long stacksize );

 PARAMETERS

     attr                Thread attributes object modified.

     stacksize           New value for the stacksize attribute.  The
                         stacksize parameter specifies the minimum size
                         (in bytes) of the stack needed for a thread.

 DESCRIPTION

 The pthread_attr_setstacksize() routine sets the minimum size (in bytes)
 of the stack needed for a thread created using the attributes object
 specified by the attr parameter. Use this routine to adjust the size of
 the writable area of the stack. The default value of the stacksize
 attribute is machine specific.

 A thread's stack is fixed at the time of thread creation. Only the main
 or initial thread can dynamically extend its stack.

 Most compilers do not check for stack overflow.  Ensure that your thread
 stack is large enough for anything that you call from the thread.

 RETURN VALUES

 If the function fails, errno may be set to one of the following values:

    Return   Error      Description
    ___________________________________________________________
    0                   Successful completion.

    -1     [EINVAL]     The value specified by attr is invalid.

    -1     [EINVAL]     The value specified by stacksize is invalid.
