pthread_key_setname_np(3)pthread_key_setname_np(3)NAMEpthread_key_setname_np - Change the object name in a thread-specific
data key object
SYNOPSIS
#include <pthread.h>
int pthread_key_setname_np(
pthread_key_t *key,
const char *name,
void *mbz );
LIBRARY
DECthreads POSIX 1003.1c Library (libpthread.so)
PARAMETERS
Address of the thread-specific data key object whose object name is to
be changed. Object name value to copy into the thread-specific data
key object. Reserved for future use. The value must be zero (0).
DESCRIPTION
This routine changes the object name in the thread-specific data key
object specified by key to the value specified by name. To set a new
thread-specific data key object's object name, call this routine imme‐
diately after initializing the key object.
The object name is a C language string and provides an identifier that
is meaningful to a person debugging a 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:
Successful completion. The value specified by key is not a valid key,
or the length in characters of name exceeds 31. Insufficient memory
exists to create a copy of the object name string.
ERRORS
None
