== Function to strip bad characters out of hostmask (to go with Kuja's ""VHostOnID"") ==

%%(c)
#include <stdio.h>
#include <string.h>
#include <ctype.h>

char* stripChars(char *string)
{
//int isalnum(int c) -- True if c is alphanumeric.
int i,j = 0,size = strlen(string);
char *result = malloc(sizeof(char) * strlen(string));

for (i = 0; i < size; i ++)
{
if (isalnum((int)string[i]))
{
result[j] = string[i];
j++;
}
}

result[j] = '\0';
return result;
}
%%

This mallocs a new string, so be sure to free if need be. I didn't want to destroy the actual buffer, because it would seem to me you need it elsewhere..
