PTHREAD_SET_NAME_NP(3) FreeBSD Library Functions Manual
NAME pthread_get_name_np, pthread_getname_np, pthread_set_name_np, pthread_setname_np - set and retrieve the thread name
LIBRARY POSIX Threads Library (libpthread, -lpthread)
SYNOPSIS #include <pthread_np.h>
void pthread_get_name_np(pthread_t thread, char *name, size_t len);
int pthread_getname_np(pthread_t thread, char *name, size_t len);
void pthread_set_name_np(pthread_t thread, const char *name);
int pthread_setname_np(pthread_t thread, const char *name);
DESCRIPTION The pthread_set_name_np() and pthread_setname_np() functions apply a copy of the given name to the given thread.
The pthread_get_name_np() and pthread_getname_np() functions retrieve the name associated with thread. If pthread_set_name_np() was not previously called for thread, the buffer pointed to by name will be empty.
ERRORS The pthread_getname_np and pthread_setname_np will fail if
[ESRCH] No thread could be found in the current process corresponding to that specified by the given thread ID thread.
Because of the debugging nature of pthread_get_name_np and pthread_set_name_np functions, all errors that may appear inside are silently ignored.
SEE ALSO thr_set_name(2), pthread_np(3)
STANDARDS pthread_set_name_np() and pthread_get_name_np() are non-standard extensions. pthread_setname_np() and pthread_getname_np() are also non- standard, but are implemented by larger number of operating systems so they are in fact more portable.
