strsep
NAME
strsep - extract token from string
SYNOPSIS
#include <string.h> I char *strsep(char ** stringp , const char * delim );
DESCRIPTION
If *stringp is NULL, the
R 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
R strsep ()
function returns a pointer to the token,
that is, it returns the original value of *stringp.
CONFORMING TO
4.4BSD
NOTES
The
R strsep ()
function was introduced as a replacement for
strtok(3),
since the latter cannot handle empty fields.
However,
strtok(3)
conforms to C89/C99 and hence is more portable.
BUGS
This function suffers from the same problems as
strtok(3).
In particular, it modifies the original string.
Avoid it.
