That's what I thought I was suggesting, something like



int myfunc(char *instring)

{

 int i;

 char *copy, *working;

 i = strlen(instring);



 /* working is a new empty string the same lenght as instring */

 if((working = malloc(i+1)) == NULL) return -1;



 /* copy is a new string that is a copy of instring, so we can

    change it without annoying the original */

 if((copy = malloc(i+1)) == NULL) return -1;

 strcpy( copy, instring);



 /* do things with the strings here, returning integers as results.

    Just ensure that all return statements are preceded by free()

    statements, like: */

 free(copy);

 free(working);

 return 0;

}



The original [100] size doesn't have to be passed to the function.



Cheers
