STRSEP(3) Linux Programmer's Manual STRSEP(3)
strsep - extract token from string
#include <string.h>
char *strsep(char **stringp, const char *delim);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
strsep(): _BSD_SOURCE
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 '\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.
The strsep() function returns a pointer to the token, that is, it returns the
original value of *stringp.
4.4BSD.
The 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.
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.
