EDIT:
New question.
Lets say I have line text wich equals "^r". I want to replace this with "" meaning i would like to delete the line, would this be possible? i've tryed fprintf and fputs but I'm not really getting anywhere with it... everytime it prints at the end of the file.

I would like doing this with the new file natives and without creating a temp file.

Current Code:
Code:
stock test() {         new data[64], fileh = fopen("addons/amxmodx/test.txt", "r+");         if ( ! fileh )         return         while ( ! feof(fileh) ) {                 fgets(fileh, data, 63);                 if ( equal(data, "^n") ) {             // ?             // fprintf(fileh, "") neither of these             // fputs(fileh, "") worked well         }             }         fclose(fileh)     }

I've tryed different modes, "r+w", "w", "a+", "a", "+"... none would work. I mean, some would read them, and some would just go on forever and read nothing and one of them would start printing some lang like "do not flood" in 5 different languages, replacing my lines.
that would be r+t
