NAME

     pthread_getname_np -- get and set descriptive name of a thread


LIBRARY

     POSIX Threads Library (libpthread, -lpthread)


SYNOPSIS

     #include <pthread.h>

     int
     pthread_getname_np(pthread_t thread, char *name, size_t len);

     int
     pthread_setname_np(pthread_t thread, const char *name, void *arg);


DESCRIPTION

     The pthread_getname_np() function obtains the descriptive name of a
     thread.  It takes the following arguments:

           thread  The thread whose descriptive name will be obtained.

           name    The buffer to be filled with the descriptive name of the
                   thread.

           len     The size of the buffer name in bytes.

     The pthread_setname_np() function sets the descriptive name of a thread.
     It takes the following arguments:

           thread  The thread whose descriptive name will be set.

           name    The printf(3) format string to be used to construct the
                   descriptive name of the thread.  The resulted descriptive
                   name should be shorter than PTHREAD_MAX_NAMELEN_NP.

           arg     The printf(3) argument used with name.


RETURN VALUES

     Both functions return 0 on success.  Otherwise, an error number is
     returned to indicate the error.

     [EINVAL]           Invalid parameter.

     [ESRCH]            Non-existent thread.

     The pthread_setname_np() function may also fail if:

     [ENOMEM]           There was insufficient memory for the operation.
