Function


SYNOPSIS

#include <pthread.h>

int pthread_setname_np(pthread_rwlock_t *rwlock, const char *name);


DESCRIPTION

The pthread_rwlock_setname_np() function assigns the specified name to the specified rwlock. This is useful for debugging purposes, so that read-write locks can be identified symbolically. If a name is specified for a rwlock, it is displayed by the NuTCRACKER Platform debugging utilities. The name can be obtained programmatically with the pthread_rwlock_getname_np() function.
