This attribute specifies theprocess sharing of the condition variable created with this attributes object. Note: The pthread.h header file must be the first included file of each source file using the threads library. Otherwise, the -D_THREAD_SAFE compilation flag should be used, or the cc_r compiler used. In this case, the flag is automatically set.Parametersattr Specifies the condition attributes object.pshared Specifies the process sharing to set. It must have one of the followingvalues:PTHREAD_PROCESS_SHARED Specifies that the condition variable can be used by any thread that has access to the memory where it is allocated, even if these threads belong to different processes.PTHREAD_PROCESS_PRIVATE Specifies that the condition variable shall only be used by threads within the same process as the thread that created it. This is the default value.Return ValuesUpon successful completion, 0 is returned. Otherwise, an error code is returned.Error CodesThe pthread_condattr_setpshared subroutine is unsuccessful if the following istrue:EINVAL The attr or pshared parameters are not valid.Implementation SpecificsThis subroutine is part of the Base Operating System (BOS) Runtime.Related InformationThe pthread_condattr_getpshared subroutine, pthread_condattr_init subroutine,pthread_cond_init subroutine.Advanced Attributes in AIX Version 4.3 General Programming Concepts: Writing andDebugging Programs.Threads Library Options in AIX Version 4.3 General Programming Concepts: Writingand Debugging Programs.Threads Library Quick Reference in AIX Version 4.3 General Programming Concepts:Writing and Debugging Programs.--------------------------------------------------------------------------------
