- /*
- * ------------------------------------------------------
- * DOCPUBLIC
- * Rwlocks created with 'attr' can be shared between
- * processes if pthread_rwlock_t variable is allocated
- * in memory shared by these processes.
- *
- * PARAMETERS
- * attr
- * pointer to an instance of pthread_rwlockattr_t
- *
- * pshared
- * must be one of:
- *
- * PTHREAD_PROCESS_SHARED
- * May be shared if in shared memory
- *
- * PTHREAD_PROCESS_PRIVATE
- * Cannot be shared.
- *
- * DESCRIPTION
- * Rwlocks creatd with 'attr' can be shared between
- * processes if pthread_rwlock_t variable is allocated
- * in memory shared by these processes.
- *
- * NOTES:
- * 1) pshared rwlocks MUST be allocated in shared
- * memory.
- *
- * 2) The following macro is defined if shared rwlocks
- * are supported:
- * _POSIX_THREAD_PROCESS_SHARED
- *
- * RESULTS
- * 0 successfully set attribute,
- * EINVAL 'attr' or pshared is invalid,
- * ENOSYS PTHREAD_PROCESS_SHARED not supported,
- *
