NAME
     pthread_attr_getname_np, pthread_attr_setname_np - get and set
     descriptive name of an attribute

LIBRARY
     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS
     #include <pthread.h>

     int
     pthread_attr_getname_np(const pthread_attr_t attr, char *name,
         size_t len);

     int
     pthread_attr_setname_np(pthread_attr_t attr, const char *name,
         void *arg);

DESCRIPTION
     The pthread_attr_getname_np() function gets the descriptive name of a
     thread attribute.  It takes the following arguments:

           attr    The attribute whose descriptive name will be obtained.

                   attribute.

           len     The size of the buffer name in bytes.

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

           attr  The attribute whose descriptive name will be set.

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

           arg   The printf(3) argument used with name.

     returned.

COMPATIBILITY

     No errors are defined for pthread_attr_getname_np().

     The pthread_attr_setname_np() function may fail if:
