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():
    Since glibc 2.19:
        _DEFAULT_SOURCE
    Glibc 2.19 and earlier:
        _BSD_SOURCE  

DESCRIPTION

If *stringpis NULL, the strsep() function returns NULL and does nothing else. Otherwise, this function finds the first token in the string *stringp, that is delimited by one of the bytes in the string delim. This token is terminated by overwriting the delimiter with a null byte (aq\0aq), and *stringpis updated to point past the token. In case no delimiter was found, the token is taken to be the entire string *stringp, and *stringpis made NULL.  

RETURN VALUE

The strsep() function returns a pointer to the token, that is, it returns the original value of *stringp.  

ATTRIBUTES

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) conforms 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.
