Ummm probably the wrong group to post this too, but hey.
I don't parse command line arguments by hand anymore. I usually use something like getopt which does the work for me and gets me out of the complexities of doing this kind of thing. That said, I think the solution to your problem is the following:
The string you are trying to parse is "TEST=-YES"
Assuming that the whole thing is in argv[2] then what you really want to do is something like this:
#include <stdio.h>
#include <strings.h>
main(argc, argv)
int argc;
char **argv;
{
char *ptr;
char tmp[80];
strcpy(tmp, argv[2]);
ptr = index(tmp, '=');
ptr++;
if (strcmp(ptr, "-YES") == 0) {
/* equal continue processing */
printf("yes\n");
}
}
I checked that this actually works. :-)

I've got the following routine I was trying to make dynamic but because my programming knowledge is as good as most I've run into a brick wall.
Here's my routine
int config(int argc, char *argv[])
bool match = false;
if (argc == 4) {
if (strncmp("TEST=-YES", buffer, strlen("TEST=-YES"))) {
Here's what I'm trying to achieve, argv[2] holds the string in question I want to test
int config(int argc, char *argv[])
bool match = false;
if (argc == 4) {
if (strncmp(argv["=-YES", buffer, strlen(argv["=-YES"))) {
but obviously this is wrong.
Can someone with better knowledge show me what would be correct please?
