PTHREAD_ATTR_GETNAME_NP(3)				   BSD Library Functions Manual 				PTHREAD_ATTR_GETNAME_NP(3)

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.

NAME

       pthread_attr_getname_np - Obtain the object name attribute in a thread attributes object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

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

PARAMETERS

       Address of the thread attributes object whose object name attribute is to be obtained.  Location to store the obtained object name.  Length
       in bytes of buffer at the location specified by name.  Reserved for future use. The value must be zero (0).

DESCRIPTION

       This routine copies the object name attribute from the thread attributes object specified by attr to  the  buffer  at  the  location  name.
       Before  calling	this  routine,	your  program must allocate the buffer indicated by name. A new thread created using the thread attributes
       object is initialized with the object name that was set in that attributes object.

       The object name is a C language string and provides an identifier that is meaningful to a person debugging a DECthreads-based multithreaded
       application.  The maximum number of characters in the object name is 31.

       If  the	specified  thread  attributes object has not been previously set with an object name, this routine copies a C language null string
       into the buffer at location name.

       This routine contrasts with pthread_getname_np, which obtains the object name from the thread object for an existing thread.

RETURN VALUES

       If an error condition occurs, this routine returns an integer value indicating the type of error.  Possible return values are  as  follows:
       Successful completion.  The value specified by attr is invalid.

ERRORS

       None
