Manual Section... (3) - page: strsep
NAMEstrsep - 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)):
DESCRIPTIONIf *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.
RETURN VALUEThe strsep() function returns a pointer to the token, that is, it returns the original value of *stringp.
NOTESThe 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.
BUGSBe 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.
