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
