NAME

pthread_cond_setname_np − Changes the object name in a condition variable object

SYNOPSIS

#include <pthread.h>
int pthread_cond_setname_np(
        pthread_cond_t ∗cond,
        const char ∗name,
        void ∗mbz );

LIBRARY

DECthreads POSIX 1003.1c Library (libpthread.so)

PARAMETERS

cond
Condition variable object whose object name is to be changed.

name
Object name value to copy into the condition variable object.

mbzReserved for future use. The value must be zero (0). 

DESCRIPTION

This routine changes the object name in the condition variable object specified by cond to the value specified by name.  To set a new condition variable object’s object name, call this routine immediately after initializing the condition variable 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. 

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 cond 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
