506	psArgument prototype code	Paul Price	David.Robbins@…	"I will attach here prototype code for psArgument.  There is a memory leak in
psArgumentParse that I haven't been able to put my finger on.

I don't think the definitions for these are in the SDRS for the current cycle,
but they will be in the next one.  The idea is to provide some simple handling
of command-line arguments using psLib.

An example use case follows:

int main(int argc, char *argv[])
{
    // Parse optional command-line arguments
    psMetadata *arguments = psMetadataAlloc(); // The arguments, with default values
    psMetadataAdd(arguments, PS_LIST_TAIL, ""-string"", PS_META_STR, ""Test
string"", ""SomeString"");
    psMetadataAdd(arguments, PS_LIST_TAIL, ""-bool"", PS_META_BOOL, ""Test bool"",
false);
    psMetadataAdd(arguments, PS_LIST_TAIL, ""-int"", PS_META_S32 |
PS_META_DUPLICATE_OK, ""Test integer 1"", 1);
    psMetadataAdd(arguments, PS_LIST_TAIL, ""-int"", PS_META_S32 |
PS_META_DUPLICATE_OK, ""Test integer 2"", 2);
    psMetadataAdd(arguments, PS_LIST_TAIL, ""-int"", PS_META_S32 |
PS_META_DUPLICATE_OK, ""Test integer 3"", 3);
    psMetadataAdd(arguments, PS_LIST_TAIL, ""-float"", PS_META_F32, ""Test float"",
1.234567);
    if (! psArgumentParse(arguments, &argc, argv) || argc != 3) {
	printf(""\nName of the program here\n\n"");
	printf(""Usage: %s INPUT OUTPUT\n\n"", argv[0]);
	psArgumentHelp(arguments);
	psFree(arguments);
	exit(EXIT_FAILURE);
    }
    const char *inputName = argv[1];	// Name of input
    const char *outputName = argv[2];	// Name of output
    printf(""Success: %s %s\n"", inputName, outputName);

    psString string = psMetadataLookupString(NULL, arguments, ""-string"");
    float floating = psMetadataLookupF32(NULL, arguments, ""-float"");
    bool boolean = psMetadataLookupBool(NULL, arguments, ""-truth"");
    printf(""String: %s\n"", string);
    printf(""Float: %f\n"", floating);
    printf(""Boolean: %d\n"", boolean);

    psMetadataItem *intItem = psMetadataLookup(arguments, ""-int"");
    if (intItem->type == PS_META_MULTI) {
	psList *intMulti = intItem->data.V;
	psListIterator *intIter = psListIteratorAlloc(intMulti, PS_LIST_HEAD, false);
	psMetadataItem *intMultiItem = NULL;
	while (intMultiItem = psListGetAndIncrement(intIter)) {
	    printf(""Integer: %d\n"", intMultiItem->data.S32);
	}
	psFree(intIter);
    }
