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

threadThread object whose object name is to be obtained. 

nameLocation to store the obtained object name. 

lenLength 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 buffer 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:

0Successful completion. 

[EINVAL]The thread specified by thread does not exist. 

ERRORS

None
