pthread_mutex_setname_np(3)pthread_mutex_setname_np(3)NAMEpthread_mutex_setname_np - Changes the object name in a mutex object
SYNOPSIS
#include <pthread.h>
int pthread_mutex_setname_np(
pthread_mutex_t *mutex,
const char *name,
void *mbz );
LIBRARY
DECthreads POSIX 1003.1c Library (libpthread.so)
PARAMETERS
Mutex object whose object name is to be changed. Object name value to
copy into the mutex object. Reserved for future use. The value must be
zero (0).
DESCRIPTION
This routine changes the object name in the mutex object specified by
mutex to the value specified by name. To set a new mutex object's
object name, call this routine immediately after initializing the mutex
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 mutex 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
