pthread_rwlock_setname_np - Changes the object name in a read-write lock object.
DECthreads POSIX 1003.1c Library (libpthread.so)
const char *name,
Read-write lock object whose object name is to be changed. Object name value to copy into the read-write lock object. Reserved for future use. The value must be zero (0).
This routine changes the object name in the read-write lock object specified by rwlock to the value specified by name. To set a new read-write lock object's object name, call this routine immediately after initializing the read-write lock object.
The object name is a C language string and provides an identifier that is meaningful to a person debugging a DECthreads-based multithreaded application. The maximum number of characters in the object name is 31.
If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows: Successful completion. The value specified by rwlock is invalid, or the length in characters of name exceeds 31. Insufficient memory exists to create a copy of the object name string.
