psArgument prototype code

[Paul Price]

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);

}

How was this bug fixed?

[David.Robbins@…]

I'm sorry, I didn't realize at the time that I was suppose to post the fix too
and I've forgotten exactly what I did. I have a strong inclination to say that
the memory leak was simply due to a missing psFree call or two. I have tests
implemented to check these functions and there are no memory leaks. That being
said, if you'd like me to spend some time testing this code segment again just
let me know. Sorry about the confusion.
