pthread_rwlock_setname_np(3)pthread_rwlock_setname_np(3)NAMEpthread_rwlock_setname_np - Changes the object name in a read-write
lock object
SYNOPSIS
#include <pthread.h>
int pthread_rwlock_setname_np(
pthread_rwlock_t *rwlock,
const char *name,
void *mbz );
LIBRARY
DECthreads POSIX 1003.1c Library (libpthread.so)
PARAMETERS
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).
DESCRIPTION
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.
RETURN VALUES
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.
ERRORS
None
