pthread_cond_setname_np(3)


NAME

  pthread_cond_setname_np - Changes the object name in a condition variable
  object.


LIBRARY

  DECthreads POSIX 1003.1c Library (libpthread.so)


SYNOPSIS

  #include <pthread.h>

  int	pthread_cond_setname_np(
			pthread_cond_t		  *cond,
			const char		  *name,
			void			  *mbz);


PARAMETERS

  cond	    Condition variable object whose object name is to be changed.

  name	    Object name value to copy into the condition variable object.

  mbz	    Reserved for future use. The value must be zero (0).


DESCRIPTION

  This routine changes the object name in the condition variable object
  specified by cond to the value specified by name. To set a new condition
  variable object's object name, call this routine immediately after
  initializing the condition variable 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.


RETURN VALUES

  If an error condition occurs, this routine returns an integer value
  indicating the type of error.	 Possible return values are as follows:

  0	    Successful completion.

  [EINVAL]  The value specified by cond is invalid, or the length in
	    characters of name exceeds 31.

  [ENOMEM]  Insufficient memory exists to create a copy of the object name
	    string.





ERRORS

  None
