PTHREAD_MUTEXATTR_G... FreeBSD Library Functions Manual PTHREAD_MUTEXATTR_G...
pthread_mutexattr_getkind_np, pthread_mutexattr_setkind_np -- mutex
attribute operations (legacy)
Reentrant C Library (libc_r, -lc_r)
#include <pthread_np.h>
int
pthread_mutexattr_getkind_np(pthread_mutexattr_t attr);
int
pthread_mutexattr_setkind_np(pthread_mutexattr_t *attr, int kind);
These functions are deprecated and non-portable implementation of the
mutex type manipulation.
It is recommended to use the pthread_mutexattr_gettype(3) and
pthread_mutexattr_settype(3) functions instead.
The pthread_mutexattr_getkind_np() function returns a positive value representing
the ``kind'' of the mutex attribute attr if successful; otherwise
the value -1 is returned and the global variable errno is set to
indicate the error.
The pthread_mutexattr_setkind_np() function returns the value 0 if successful;
otherwise the value -1 is returned and the global variable errno
is set to indicate the error.
The pthread_mutexattr_getkind_np() and pthread_mutexattr_setkind_np()
functions will fail if:
[EINVAL] The value specified by attr is invalid.
