strsep - extract token from string

SYNOPSIS

       #include <string.h>

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

DESCRIPTION

       The  strsep()  function  returns  the  next token from the
       string stringp which is delimited by delim.  The token  is
       terminated with a `\0' character and stringp is updated to
       point past the token.

RETURN VALUE

       The strsep() function returns a pointer to the  token,  or
       NULL if delim is not found in 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.)
