PTHREAD_RWLOCKATTR_GETPSHARED(3)			   BSD Library Functions Manual 			  PTHREAD_RWLOCKATTR_GETPSHARED(3)

NAME
pthread_rwlockattr_getpshared -- get the process shared attribute SYNOPSIS
#include <pthread.h> int pthread_rwlockattr_getpshared(const pthread_rwlockattr_t *restrict attr, int *restrict pshared); DESCRIPTION
The pthread_rwlockattr_getpshared() function is used to get the process-shared setting of a read/write lock attribute object. The setting is returned via pshared, and may be one of two values: PTHREAD_PROCESS_SHARED Any thread of any process that has access to the memory where the read/write lock resides can manipulate the lock. PTHREAD_PROCESS_PRIVATE Only threads created within the same process as the thread that initialized the read/write lock can manipulate the lock. This is the default value. RETURN VALUES
If successful, the pthread_rwlockattr_getpshared() function will return zero. Otherwise, an error number will be returned to indicate the error. SEE ALSO
pthread_rwlock_init(3), pthread_rwlockattr_init(3), pthread_rwlockattr_setpshared(3) STANDARDS
The pthread_rwlockattr_getpshared() function is expected to conform to Version 2 of the Single UNIX Specification (``SUSv2''). ERRORS
pthread_rwlockattr_getpshared() may fail if: [EINVAL] The value specified by attr is invalid. HISTORY
The pthread_rwlockattr_getpshared() function first appeared in FreeBSD 3.0. BSD
March 22, 1999 BSD
