Hi All,

  A function that has a prototype of:

char * strrchr( char * str, int ch );

  It takes a character as an int in that second param.
 
  I am having trouble using it with a #define's VAR.

---
#define DIRMARK "/"

...

char * filename = strrchr(path, DIRMARK);
fprintf(stderr, "debug: filename = %s\n", filename);
---

gcc complains:
warning: passing arg 2 of `strrchr' makes integer from pointer without a cast

  It compiles, but doesn't seem to work right:

debug: filename = (null)


Any suggestions?
