pthread_getname_np(3)					     Library Functions Manual					     pthread_getname_np(3)

NAME

       pthread_getname_np - Obtain the object name from the thread object of an existing thread.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_getname_np(
			     pthread_thread_t	       thread,
			     char		       *name,
			     size_t		       len);

PARAMETERS

       Thread  object whose object name is to be obtained.  Location to store the obtained object name.  Length in bytes of buffer at the location
       specified by name.

DESCRIPTION

       This routine copies the object name from the thread object specified by thread to the buffer at the location  name.   Before  calling  this
       routine, your program must allocate the buffer indicated by name.

       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 object has not been previously set with an object name, this routine copies a C language null string into the  buf-
       fer at location name.

       This  routine contrasts with pthread_attr_getname_np, which obtains 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.

ERRORS

       None

pthread_attr_setname_np(3)				     Library Functions Manual					pthread_attr_setname_np(3)

NAME

       pthread_attr_setname_np - Change the object name attribute in a thread attributes object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

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

PARAMETERS

       Address of the thread attributes object whose object name attribute is to be changed.  Object name value to copy into the thread attributes
       object's object name attribute.	Reserved for future use. The value must be zero (0).

DESCRIPTION

       This routine changes the object name attribute in the thread attributes object specified by attr to the value  specified  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.

       This routine contrasts with pthread_setname_np, which changes the object name in 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, or the length in characters of name exceeds 31.	Insufficient memory exists
       to create a copy of the object name string.

ERRORS

       None
