PTHREAD_RWLOCKATTR_SETPSHARED(3) OpenBSD Programmer's Manual PTHREAD_RWLOCKATTR_SETPSHARED(3)

NAME
     pthread_rwlockattr_setpshared - set the process shared attribute



SYNOPSIS
     #include <pthread.h>

     int
     pthread_rwlockattr_setpshared(pthread_rwlockattr_t *attr, int *pshared);

DESCRIPTION
     The pthread_rwlockattr_setpshared() function sets the process shared at-
     tribute of attr to the value referenced by pshared. pshared 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 re-
                                   sides can manipulate the lock.

         PTHREAD_PROCESS_PRIVATE   Only threads created within the same pro-
                                   cess 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_setpshared() 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_rwlockat-
     tr_setpshared(3)

STANDARDS
     The pthread_rwlockattr_setpshared() function is expected to conform to
     Version 2 of the Single UNIX Specification.

ERRORS
     pthread_rwlockattr_setpshared() will fail if:

     [EINVAL]      The value specified by attr or pshared is invalid.

     The pthread_rwlockattr_setpshared() function first appeared in OpenBSD
     2.5.
