      4 /* NAME
      5 /*	split_at 3
      6 /* SUMMARY
      7 /*	trivial token splitter
      8 /* SYNOPSIS
      9 /*	#include <split_at.h>
     10 /*
     11 /*	char	*split_at(string, delimiter)
     12 /*	char	*string;
     13 /*	int	delimiter
     14 /*
     15 /*	char	*split_at_right(string, delimiter)
     16 /*	char	*string;
     17 /*	int	delimiter
     18 /* DESCRIPTION
     19 /*	split_at() null-terminates the \fIstring\fR at the first
     20 /*	occurrence of the \fIdelimiter\fR character found, and
     21 /*	returns a pointer to the remainder.
     22 /*
     23 /*	split_at_right() looks for the rightmost delimiter
     24 /*	occurrence, but is otherwise identical to split_at().
     25 /* DIAGNOSTICS
     26 /*	The result is a null pointer when the delimiter character
     27 /*	was not found.
