    STRSEP(3)	    UNIX Programmer's Manual		STRSEP(3)

    NAME
         strsep - separate strings

    SYNOPSIS
         #include <string.h>

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

    DESCRIPTION
         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.

         An ``empty'' field, i.e. one caused by two adjacent delim-
         iter characters, can be detected by comparing the location
         referenced by the pointer returned in *stringp to `\0'.

         If *stringp is initially NULL, strsep() returns NULL.

    EXAMPLES
         The following uses strsep() to parse a string, containing
         tokens delimited by white space, into an argument vector:

         char **ap, *argv[10], *inputstring;

         for (ap = argv; (*ap = strsep(&inputstring, " \t")) != NULL;)
    	  if (**ap != '\0')
    	       ++ap;

    HISTORY
         The strsep() function is intended as a replacement for the
         strtok() function.  While the strtok() function should be
         preferred for portability reasons (it conforms to ANSI C
         X3.159-1989 (``ANSI C'')) it is unable to handle empty
         fields, i.e. detect fields delimited by two adjacent delim-
         iter characters, or to be used for more than a single string
         at a time.  The strsep() function first appeared in 4.4BSD.
