strsep - extract token from string
char *strsep(char **stringp, const char *delim);
Feature Test Macro Requirements for glibc (see
If *stringp is NULL, the
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.
function returns a pointer to the token,
that is, it returns the original value of *stringp.
function was introduced as a replacement for
since the latter cannot handle empty fields.
conforms to C89/C99 and hence is more portable.
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.
