pthread_mutexattr_gettype(3) Library Functions Manual pthread_mutexattr_gettype(3)
NAME
pthread_mutexattr_gettype - Obtains the mutex type attribute in the specified mutex attributes object.
LIBRARY
DECthreads POSIX 1003.1c Library (libpthread.so)
SYNOPSIS
#include <pthread.h>
int pthread_mutexattr_gettype(
const pthread_mutexattr_t *attr,
int *type);
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
IEEE Std 1003.1c-1995, POSIX System Application Program Interface
PARAMETERS
Mutex attributes object whose mutex type attribute is obtained. Receives the value of the mutex type attribute. The type argument speci-
fies the type of mutex that is created. Valid values are: PTHREAD_MUTEX_NORMAL PTHREAD_MUTEX_DEFAULT (default) PTHREAD_MUTEX_RECURSIVE
PTHREAD_MUTEX_ERRORCHECK
DESCRIPTION
This routine obtains the value of the mutex type attribute in the mutex attributes object specified by the attr argument and stores it in
the location specified by the type argument. See the pthread_mutexattr_settype(3) routine description for information about mutex type
attributes.
RETURN VALUES
On successful completion, this routine returns the mutex type in the location by the type argument.
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 attr is invalid.
ERRORS
None
