pthread_mutexattr_getkind_np(3)

NAME

     pthread_mutexattr_getkind_np, pthread_mutexattr_setkind_np -- mutex
     attribute operations (legacy)

LIBRARY

     Reentrant C Library (libc_r, -lc_r)
     POSIX Threads Library (libpthread, -lpthread)
     1:1 Threading Library (libthr, -lthr)

SYNOPSIS

     #include <pthread_np.h>

     int
     pthread_mutexattr_getkind_np(pthread_mutexattr_t attr);

     int
     pthread_mutexattr_setkind_np(pthread_mutexattr_t *attr, int kind);

DESCRIPTION

     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.

RETURN VALUES

     The pthread_mutexattr_getkind_np() function returns a positive value rep-
     resenting the ``kind'' of the mutex attribute attr if successful; other-
     wise 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 suc-
     cessful; otherwise the value -1 is returned and the global variable errno
     is set to indicate the error.

ERRORS

     The pthread_mutexattr_getkind_np() and pthread_mutexattr_setkind_np()
     functions will fail if:

     [EINVAL]		The value specified by attr is invalid.
