NAME

       strsep - extract token from string

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 `' 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()  con-
       forms 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.
