!!NAME


strsep - extract token from string
!!SYNOPSIS


__#include
__''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''.
!!NOTES


The __strsep()__ function was introduced as a replacement
for __strtok()__, since the latter cannot handle empty
fields. However, __strtok()__ conforms to ANSI-C and
hence is more portable.
!!BUGS


This function suffers from the same problems as
__strtok()__. In particular, it modifies the original
string. Avoid it.
