    NAME
        CsrLogLevelTextSet

    DESCRIPTION
        Set the text logging level for a given origin and optionally sub origin
        by name. If either string is NULL or zero length, it is interpreted as
        all origins and/or all sub origins respectively. If originName is NULL
        or zero length, subOriginName is ignored.

        Passing NULL or zero length strings in both originName and subOriginName
        is equivalent to calling CsrLogLevelTextSetAll, and overrides all
        previous filter configurations for all origins and sub origins.

        Passing NULL or a zero length string in subOriginName overrides all
        previous filter configurations for all sub origins of the specified
        origin.

        Note: the supplied strings may be accessed after the function returns
        and must remain valid and constant until CsrLogDeinit is called.

        Note: when specifying an origin (originName is not NULL and not zero
        length), this function can only be used for origins that use the
        csr_log_text_2.h interface for registration and logging. Filtering for
        origins that use the legacy csr_log_text.h interface must be be
        configured using the legacy filter configuration functions that accept
        a CsrLogTextTaskId as origin specifier. However, when not specifying an
        origin this function also affects origins that have been registered with
        the legacy csr_log_text.h interface. Furthermore, using this function
        and the legacy filter configuration functions on the same origin is not
        allowed.

    PARAMETERS
        originName - a string containing the name of the origin. Can be NULL or
            zero length to set the log level for all origins. In this case, the
            subOriginName parameter will be ignored.
        subOriginName - a string containing the name of the sub origin. Can be
            NULL or zero length to set the log level for all sub origins of the
            specified origin.
        warningLevelMask - The desired log level for the specified origin(s) and
            sub origin(s).
