       Proposal Attached: Y_ Yes __ No, but what's your interest?
       Abstract:

       1: Strtok cannot handle empty fields.
       2: Strtok cannot handle more than a single string at a time.
       
       Proposal:

       Provide strsep as a replacement.

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

       The strsep() function locates, in the string referenced
       by *stringp, the first occurrence of any character in
       the string delim (or the terminating `\0' character) and
       replaces it with a `\0'.  The location of the next
       character after the delimiter character (or NULL, if the
       end of the string was reached) is stored in *stringp.
       The original value of *stringp is returned.
