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

attrAddress of the thread attributes object whose object name attribute is to be changed. 

nameObject name value to copy into the thread attributes object’s object name attribute. 

mbzReserved 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:

0Successful completion. 

[EINVAL]The value specified by attr 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
