  pthread_attr_getschedparam()

  NAME

    pthread_attr_getschedparam(), pthread_attr_setschedparam() - get or set
    the thread scheduling parameters attribute

  SYNOPSIS

    #include 

    int pthread_attr_getschedparam(const pthread_attr_t *attr, struct
    sched_param *param);
    int pthread_attr_setschedparam(pthread_attr_t *attr, const struct
    sched_param *param);

  DESCRIPTION

    The pthread_attr_setschedparam(2) sets the scheduling parameters attribute
    in the thread attributes object referenced by attr by using the values in
    the sched_param structure referenced by the param argument. The
    sched_param structure, defined in  contains the following fields:

    struct sched_param {
        int     sched_priority; /* scheduling priority */
        int     sched_nicelim;  /* nice value limit for SCHED_OTHER policy */
        int     sched_nice;     /* nice value for SCHED_OTHER policy */
        int     sched_pad[6];   /* this is used for padding */
    };

    After the attributes have been set in the thread attributes object
    referenced by attr, the pthread_create(2) function can be called to create
    a new thread with the specified attributes. The effective thread priority
    of the new thread is equal to the process priority (determined from the
    nice(2) value of the process) plus the thread priority that is set by this
    function. This function does not affect the current running thread.

    NOTE: In this version of Interix, only the sched_priority field of the
    sched_param structure is supported. Other fields are ignored.

    The pthread_attr_getschedparam(2) function retrieves the scheduling
    parameter attributes of the thread object referenced by attr, storing the
    value in the location referenced by the param argument.

  RETURN VALUES

    On success, both functions return 0; otherwise, they return an error
    number.

  ERRORS

    The pthread_attr_setschedparam() function can fail for the following
    reasons:

    [EINVAL]
        The param argument is invalid.

    [ENOTSUP]
        An attempt was made to set the scheduling parameters attribute to an
        unsupported value.

    Neither function returns [EINTR].
