pthread_setname_np(3)					     Library Functions Manual					     pthread_setname_np(3)

NAME

       pthread_setname_np - Changes the object name in the thread object for an existing thread.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_setname_np(
			     pthread_thread_t	       thread,
			     const char 	       *name,
			     void		       *mbz);

PARAMETERS

       Thread  object  whose  object name is to be changed.  Object name value to copy into the thread object.	Reserved for future use. The value
       must be zero (0).

DESCRIPTION

       This routine changes the object name in the thread object specified by thread to the value specified by name. To set an	existing  thread's
       object  name,  call  this routine after creating the thread. However, with this approach your program must account for the possibility that
       the target thread has already exited or has been canceled before this routine is called.

       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.

       This  routine contrasts with pthread_attr_setname_np, which changes the object name attribute in a thread attributes object that is used to
       create a new 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 thread specified by thread does not exist.  The length in characters of name exceeds 31.  Insufficient memory
       exists to create a copy of the object name string.

ERRORS

       None

pthread_attr_getname_np(3)				     Library Functions Manual					pthread_attr_getname_np(3)

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
