Strings in C

[Riley]

Okay, I opened the header file (string.h) and could not find a substr function and I need to take a string apart... What function(s) do I use?

[sans-hubris]

Use strtok to break up a string.

Well, it's already delimited I'm trying to turn it into multiple strings with the delimitors...

This seems to work.


#include <stdio.h>

#define MAX 10

char **split(char *delim, char *str);
int main(void)
{
char src[15] = "this:is:a:test";
char *delim = ":";
char **list;

list = split(delim, src);

while(*list) {
print("%s",*list++);
}

return 0;
}

char **split(char *delim, char *str)
{
static char *list[MAX];
char *begin = str;
int length = strlen(str);
int flag = 0;
int i = 0;

while(*str) {
if(*str == *delim) *str = '\0';
str++;
}


while(length && (i<MAX)) {

if((*begin != '\0') && (!flag)) {
list[i++] = begin;
flag = 1;
} else if(*begin == '\0') {
flag = 0;
}

begin++; length--;
}

return list;

}
