pthread_mutex_setname_np(3) Library Functions Manual pthread_mutex_setname_np(3)
NAME
pthread_mutex_setname_np - Changes the object name in a mutex object.
LIBRARY
DECthreads POSIX 1003.1c Library (libpthread.so)
SYNOPSIS
#include <pthread.h>
int pthread_mutex_setname_np(
pthread_mutex_t *mutex,
const char *name,
void *mbz);
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
