Thread: str_replace

Hello,

I am using the following str_replace function -:

Code:

char * str_replace(char *haystack,char *needle,char *rstr) {
   size_t size=strlen(haystack)+1;
   char *p[size+1];
   char *ptrp=p;
   char *newstr;
   char *match;
   char *replace;
   int i,j;
   if (p==NULL){
      return(p);
   }
   newstr=haystack;
   while (*newstr){
      match=needle;
      replace=rstr;
      i=0;
      while(*newstr && *match){
         if(*newstr != *match){
            *ptrp++=*newstr++;
            match=needle;
            i=0;
         } else if(*newstr==*match){
            *ptrp++=*newstr++;
            match++;
            i++;
         }
      }
      if(i==(int)strlen(needle)){
         j=0;
         while(j<i){
            ptrp--;
            j++;
         }
         while(*replace){
            *ptrp++=*replace++;
         }
      }
   }

   *ptrp='\0';
   return(p);
}

Which works great, however, it does not seems to work if I want to remove "(" or ")" characters.

Any any ideas why?
