| strtok |
(String str1, String str2) |
yoix.string |
| |
Finds the first token in the null-terminated string
str1
delimited by one of the characters from the null-terminated string
str2.
strtok
creates a new string from the delimited sub-string
and returns that string, or
NULL
when no tokens remain.
strtok
remembers its position in the current string and uses it on subsequent
calls made with the same string,
str1,
as the first argument.
Two adjacent delimiters in
str1
causes an empty string to be returned, so a sequence of calls splits
str1
into tokens delimited by characters from
str2.
The separator string
str2
can be different on each call.
String
str1
is trashed by
strtok
and should not be modified outside
strtok
if the tokenizing is expected to continue properly.

| Example: |
The program,
import yoix.stdio.*;
import yoix.string.*;
String str1 = "Say what?";
String str2 = "Hello there, world";
String delim = " ,?";
String result;
while ((result = strtok(str1, delim)) != NULL) {
printf("|%s| ", result);
while ((result = strtok(str2, delim)) != NULL) {
printf("|%s| ", result);
}
}
printf("\n");
prints
|Say| |Hello| |there| || |world| |what| ||
on standard output.
