VMS Help  —  POSIX Threads, TIS routines, tis_cond_destroy
    Destroys the specified condition variable.

1  –  C Binding

    #include <tis.h>

    int
    tis_cond_destroy (
                pthread_cond_t   *cond);

2  –  Arguments

 cond

    Address of the condition variable (passed by reference) to be
    destroyed.

3  –  Description

    This routine destroys the condition variable specified by cond.
    After this routine is called, the Threads Library may reclaim
    internal storage used by the condition variable object. Call this
    routine when a condition variable will no longer be referenced.

    The results of this routine are unpredictable if the condition
    variable specified in cond does not exist or is not initialized.

    For more information about actions when threads are present,
    refer to the pthread_cond_destroy() description.

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:

    Return      Description

    0           Successful completion.
    [EBUSY]     The object being referenced by cond is being
                referenced by another thread that is currently
                executing a
                tis_cond_wait()  on the condition variable specified
                in cond. (This error can only occur when threads are
                present.)
    [EINVAL]    The value specified by cond is not a valid condition
                variable.
