As Mark pointed out, there is a standard C fucntion for this purpose called strstr(). In CCS, the code for strstr() is in the file STRING.H located in the \Drivers directory. Open it up and take a look at the source code. You can see:
| Quote: |
/* standard template:
char *strstr(const char *s1, const char *s2);
Locates first occurence of character sequence s2 in s1;
returns 0 if s2 is empty string
Uncomment #define FASTER_BUT_MORE_ROM at the top of the
file to use the faster algorithm */ |
Defining FASTER_BUT_MORE_ROM is indeed much faster especially if you need to work on big strings, but it results in a bigger code.
However, I remember having problems with the CCS strstr and writing my own. Still, the CCS code is a good starting point. |
