STRSEP(9)						     Basic C Library Functions							 STRSEP(9)

NAME

       strsep - Split a string into tokens

SYNOPSIS

       char * strsep(char ** s, const char * ct);

ARGUMENTS

       s
	   The string to be searched

       ct
	   The characters to search for

DESCRIPTION

       strsep updates s to point after the token, ready for the next call.

       It returns empty tokens, too, behaving exactly like the libc function of that name. In fact, it was stolen from glibc2 and de-fancy-fied.
       Same semantics, slimmer shape. ;)

NAME

       strsep - extract token from string

SYNOPSIS

       #include <string.h>

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

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       strsep(): _BSD_SOURCE

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.

CONFORMING TO

       4.4BSD.

NOTES

       The strsep() function was introduced as a replacement for strtok(3), since the latter cannot handle empty fields.  However, strtok(3)  con-
       forms to C89/C99 and hence is more portable.

BUGS

       Be cautious when using this function.  If you do use it, note that:

       * This function modifies its first argument.

       * This function cannot be used on constant strings.

       * The identity of the delimiting character is lost.
