Function Documentation

int QSD_process (  int  argc, char *const   argv[], const char *  facility, const QSF_schema *  generic )

Process a file of datagrams. Returns: Overall status Parameters: argc  The argument count argv  The vector of command line strings facility  The name of the facility invoking this utility. generic  The generic or default processor to use if none is supplied via the command line Usage This utility scans an input .lsd file, processing each datagram. The datagrams are processed by attempting to dynamically load a datagram specific processor meant to be customized for both The type of datagram being processed (from the datagram's ID) and The type of processing being requested (from the facility) To this end the utility attempts to load a shareable whose name is constructed of these pieces lib<facility>_<datagram_id><variant>.so Each of these components come from a different place facility is from the calling program and is meant to define the type of processing being requested, e.g. qsd_print, for a print utility qsd_analyze, for a analysis utility datagram_id is from the datagram itself. This number is formatted as a 0-filled 5-digit hex number, e.g. f0200 or 00111. Note that the hex digits represented by letters (a-f) are formatted in lower case. variant is from the command line and is meant to indicate variations on the basic theme (i.e. a verbose print or a terse print option. This is not the greatest method since one can quickly enter permutation hell trying to build a shareable specific for each possible combination of options.
