Yup.  strsep() is your friend:

SYNOPSIS
       #include <string.h>

       char *strsep(char **stringp, const char *delim);

DESCRIPTION
       If  *stringp  is  NULL, the strsep() function returns NULL
       and does nothing else. Otherwise, this function finds  the
       first  token  in  the  string  *stringp,  where tokens are
       delimited by symbols in the string delim.  This  token  is
       terminated  with  a  `\0'  character  (by  overwriting the
       delimiter) and *stringp  is  updated  to  point  past  the
       token.  In case no delimiter was found, the token is taken
       to be the entire string *stringp,  and  *stringp  is  made
       NULL.

RETURN VALUE
       The strsep() function returns a pointer to the token, that
       is, it returns the original value of *stringp.
