NAME

pthread_mutexattr_destroy

- Destroys a mutex attributes object

LIBRARY

G-series native OSS processes: /G/system/sysnn/zsptsrl

H-series OSS processes: /G/system/zdllnnn/zsptdll

SYNOPSIS

#include <spthread.h>

int pthread_mutexattr_destroy(

pthread_mutexattr_t *

attr);

PARAMETERS

attr speciﬁes the mutex attributes object to be destroyed.

DESCRIPTION

This function destroys a mutex attributes object by unintializing it. Call this function when your

program no longer needs the speciﬁed mutex attributes object.

After this function is called, the system might reclaim the storage used by the destroyed mutex

attributes object. Destroying a mutex attributes object does not affect any mutexes that were pre-

viously created using that mutex attributes object.

NOTES

The functions to set and get the process shared attribute are not supported by this implementa-

tion.

RETURN VALUES

If an error condition occurs, this function returns an integer value indicating the type of error.

Possible return values are:

0 Successful completion.

[EINVAL] The value speciﬁed by the attr parameter is invalid. |
