pthread_mutex_getname_np(3)				     Library Functions Manual				       pthread_mutex_getname_np(3)

NAME

       pthread_mutex_getname_np - Obtain the object name from a mutex object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_mutex_getname_np(
			     pthread_mutex_t	       *mutex,
			     char		       *name,
			     size_t		       len);

PARAMETERS

       Address of the mutex 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 mutex object specified by mutex to the buffer at the location name.  Before calling this  rou-
       tine, 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 mutex object has not been previously set with an object name, this routine copies a C language null string into the buffer
       at location name.

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 mutex is invalid.

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
