pthread_mutex_getname_np - Obtain the object name from a mutex object.
DECthreads POSIX 1003.1c Library (libpthread.so)
Address of the mutex object whose object name is to be obtained. Location to store the obtained object name. Length in bytes of buffer at the location specified by name.
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 buffer at location name.
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.
