Overview

This readchar(f) function will read a character from a file with handle f. The file handle maintains its position in the file, so after a call to read char the position pointer will be incremented.

  • Pass: The File handle to read character from
  • Returns: A character from the file type Char

Example

#include <io>

function void main() {
   var f:=open("hello.txt","r");
   var u:=readchar(f);
   close(f); 
};
