rpc_ss_get_thread_handle(3rpc)  —  Subroutines

NAME

rpc_ss_get_thread_handle — Gets a thread handle for the manager code before it spawns additional threads, or for the client code when it becomes a server;  used by server or possibly by client applications

Synopsis

rpc_ss_thread_handle_t rpc_ss_get_thread_handle(
void);

Description

The rpc_ss_get_thread_handle() routine is used by a server manager thread when it spawns additional threads.  To spawn additional threads that are able to perform memory management, the server manager code calls rpc_ss_get_thread_handle() and passes the thread handle to each spawned thread.  Each spawned thread that uses rpc_ss_allocate() and rpc_ss_free() for memory management must first call rpc_ss_set_thread_handle(), using the handle obtained by the original manager thread. 

The rpc_ss_get_thread_handle() routine can also be used when a program changes from being a client to being a server.  The program gets a handle on its environment as a client by calling rpc_ss_get_thread_handle().  When the program reverts to being a client it re−establishes the client environment by calling rpc_ss_set_thread_handle(), supplying the previously obtained handle as a parameter. 

Return Values

A thread handle. 

Examples

This function determines the thread handle, creates a thread, and passes the thread handle to the thread so it can share the memory management environment of the calling thread. 

#include <pthread.h>
 
#include <idlbase.h>

pthread_t Launch_thread(
    int (∗routine_to_launch)(
       pthread_addr_t th
       )
    )
 
{
    rpc_ss_thread_handle_t th = rpc_ss_get_thread_handle();
    pthread_t t;

    /∗
     ∗ Create the thread and pass to it the thread handle
     ∗ so it can use rpc_ss_set_thread_handle.
     ∗/
    pthread_create (&t, pthread_attr_default,
        (pthread_startroutine_t)routine_to_launch,
        (pthread_addr_t)th);

    return t;
 
}
