pthread_attr_getname_np(3)


NAME

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


SYNOPSIS

  #include <pthread.h>

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


LIBRARY

  DECthreads POSIX 1003.1c Library (libpthread.so)


PARAMETERS

  attr
      Address of the thread attributes object whose object name attribute is
      to be obtained.

  name
      Location to store the obtained object name.

  len Length in bytes of buffer at the location specified by name.

  mbz 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:

  0   Successful completion.

  [EINVAL]
      The value specified by attr is invalid.


ERRORS

  None
