It will return the "=ny" part, so incrementing it one from there will make it return the "ny" part. This assumes that the string includes '=' in it, if it doesn't it will break. But that's taken care of by prefix.

thanks!

but the catch here (which I just realized) is I need to know if they ever pass just "markid=". This means they want to clear the field....

So with the above suggestion, when they passed in "markid=", I would get NULL I assume?

STRCHR(3)						     Linux Programmer's Manual							 STRCHR(3)

NAME

       strchr, strrchr - locate character in string

SYNOPSIS

       #include <string.h>

       char *strchr(const char *s, int c);

       char *strrchr(const char *s, int c);

DESCRIPTION

       The strchr() function returns a pointer to the first occurrence of the character c in the string s.

       The strrchr() function returns a pointer to the last occurrence of the character c in the string s.

       Here "character" means "byte" - these functions do not work with wide or multi-byte characters.

RETURN VALUE

       The strchr() and strrchr() functions return a pointer to the matched character or NULL if the character is not found.
