Obtains the mutex type attribute in the specified mutex attribute
    object.

1  –  C Binding

    #include <pthread.h>

    int
    pthread_mutexattr_gettype (
                const pthread_mutexattr_t   *attr,
                int   *type);

2  –  Arguments

 attr

    Mutex attributes object whose mutex type attribute is obtained.

 type

    Receives the value of the mutex type attribute. The type argument
    specifies the type of mutex that can be created. Valid values
    are:

       PTHREAD_MUTEX_NORMAL
       PTHREAD_MUTEX_DEFAULT (default)
       PTHREAD_MUTEX_RECURSIVE
       PTHREAD_MUTEX_ERRORCHECK

3  –  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() description for information about
    mutex types.

4  –  Return Values

    On successful completion, this routine returns the mutex type in
    the location specified by the type argument.

    If an error condition occurs, this routine returns an integer
    value indicating the type of the error. Possible return values
    are as follows:

    Return      Description

    0           Successful completion.
    [EINVAL]    The value specified by attr is not a valid mutex
                attributes object.
