standard.C.io.fputc

Name	Version	Deprecated
fputc	version 1.0	no

Prototype:

string fputc(string ch, number fd)

Parameters:

ch	[in] Character to be written
fd	[in] A valid file descriptor

Description:

fputc writes the single character ch to a file at the position indicated by the associated file position indicator (if defined) and advances the indicator as appropriate; the file is associated with fd. If the file cannot support positioning requests or was opened in append mode, the character is appended to the end of the stream.

Example:

import standard.C.io



define FILENAME "test.txt"



class Main {

     function Main() {

          var fd; 

          var ch;

          var i;

          var buffer = "Test of fputc\n"; 



          // Open file for write 

          if (fd = fopen(FILENAME, "w")) { 

               // Print line to stream using fputc

               ch = buffer[0];

               i = 0;

               while (ch) {

                    fputc(ch, fd);

                    i++;

                    ch = buffer[i];

               }



               freopen(FILENAME, "r", fd);

               buffer = "";

               fread(buffer, 1, 15, fd);



               echo "$buffer\n";

               fclose(fd);

          } else

               echo "Problem opening the file\n"; 

     }

}
