NAME

     pthread_attr_getname_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.

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


RETURN VALUES

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


COMPATIBILITY

     Both functions are non-standard extensions.


ERRORS

     No errors are defined for pthread_attr_getname_np().

     The pthread_attr_setname_np() function may fail if:

     [EINVAL]           The supplied descriptive name was longer than
                        PTHREAD_MAX_NAMELEN_NP.

     [ENOMEM]           There was insufficient memory for the operation.
