1  –  C Binding

    #include <pthread.h>

    int
    pthread_attr_getdetachstate (
                const pthread_attr_t   *attr,
                int   *detachstate);

2  –  Arguments

 attr

    Thread attributes object whose detachstate attribute is obtained.

 detachstate

    Receives the value of the detachstate attribute.

3  –  Description

    This routine obtains the detachstate attribute of a thread
    attributes object. This attribute specifies whether threads
    created using the specified thread attributes object are created
    in a detached state.

    On successful completion, this routine returns a zero and the
    detachstate attribute is set in detachstate. A value of PTHREAD_
    CREATE_JOINABLE indicates the thread is not detached, and a value
    of PTHREAD_CREATE_DETACHED indicates the thread is detached.

    See the pthread_attr_setdetachstate() description for information
    about the detachstate attribute.

4  –  Return Values

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