Hi,

I am dealing with the http header. it is basically made up of pairs like teh
following:

key: value\n\r
key: value\n\r
key: value\n\r

Now, I need to capture those values and push them into an associative array,
so basically I am going to use std::string this way:

#include <string>
#include <map>
using namespace std;

map<string, string> header;

Yet, since I am quite new to std::string I'd like to know how to split one
line based on ": ", then I am goit to remove any extra whitespaces by using
my
own chomp()

thanks

why not consider the C language?

doLine routine should be done in assembly

#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#define u8 unsigned char

int doLine(u8** p1, u8** p2, u8* line)
{u8 *p;
if(line==0) return 0;
*p1=p=line; *p2=0;
for(; *p; ++p)
     if(*p==':' && p[1]==' ')
            {*p=0; *p2=p+2;}
if(*p2==0) return 0;
for(--p; p>=*p2 && isspace(*p); --p)
                   *p=0;
if(**p2==0) return 0;
return 1;
}

int main(void)
{u8 line[]=" key : value \r\n";
u8 *p1, *p2;
if(doLine(&p1, &p2, line)==0)
              printf("Error of line\n");
else printf("%s->%s\n", p1, p2);
return 0;
}
