pthread_mutex_getname_np(3)pthread_mutex_getname_np(3)NAMEpthread_mutex_getname_np - Obtain the object name from a mutex object
SYNOPSIS
#include <pthread.h>
int pthread_mutex_getname_np(
pthread_mutex_t *mutex,
char *name,
size_t len );
LIBRARY
DECthreads POSIX 1003.1c Library (libpthread.so)
PARAMETERS
Address of the mutex object whose object name is to be obtained. Loca‐
tion to store the obtained object name. Length in bytes of buffer at
the location specified by name.
DESCRIPTION
This routine copies the object name from the mutex object specified by
mutex to the buffer at the location name. Before calling this routine,
your program must allocate the buffer indicated by name.
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 the specified mutex object has not been previously set with an
object name, this routine copies a C language null string into the buf‐
fer at location name.
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.
ERRORS
None
