NAME
rpc_sm_allocate - Allocates memory within the RPC stub memory
management scheme
SYNOPSIS
#include <rpc.h>
idl_void_p_t rpc_sm_allocate ( unsigned long size,
unsigned32 *status );
PARAMETERS
Input
size Specifies, in bytes, the size of memory to be allocated.
Output
status Returns the status code from this routine. This status code
indicates whether the routine completed successfully or, if
not, why not.
Possible status codes and their meanings include:
rpc_s_ok Success.
DESCRIPTION
Applications call rpc_sm_allocate to allocate memory within the RPC
stub memory management scheme. Before a call to this routine, the
stub memory management environment must have been established. For
manager code that is called from the stub, the stub itself normally
establishes the necessary environment. When rpc_sm_allocate is used
by code that is not called from the stub, the application must
establish the required memory management environment by calling
rpc_sm_enable_allocate.
When the stub establishes the memory management environment, the stub
itself frees any memory allocated by rpc_sm_allocate. The application
can free such memory before returning to the calling stub by calling
rpc_sm_free.
When the application establishes the memory management environment,
it must free any memory allocated, either by calling rpc_sm_free or
by calling rpc_sm_disable_allocate.
Multiple threads may call rpc_sm_allocate and rpc_sm_free to manage
the same memory within the stub memory management environment. To do
so, the threads must share the same stub memory management thread
handle. Applications pass thread handles from thread to thread by
calling rpc_sm_get_thread_handle and rpc_sm_set_thread_handle.
RETURN VALUES
A pointer to the allocated memory.
