Need an idea

[Onkel BeBu]

Hi i got following problem:

I get a string which consists of substrings seperated by :
In fact they can look like one of these

POS:X:DIST:IMM
POS:DIST:IMM
POS:IMM

but these three are comlpetly the same and i have to call the same function afterwards. Now my question is if i have to test in an if question all the three cases or if there is a better way?

[Prelude]

POS:X:DIST:IMM
POS:DIST:IMM
POS:IMM

If all three are the same then you really only need the first and last items. Something like this:

char *last = strrchr ( s, ':' ) + 1;
char *first = strchr ( s, ':' );
*first = '\0';
first = s;
/* Now first points to "POS" and last points to "IMM" */

Of course, you would need to add error checking. And if the original cannot be modified, some copying would need to be done as well.
