SYNOPSIS

#include <stdio.h>

int fputc(int c, FILE *f);

DESCRIPTION

fputc writes a single character c to the stream associated with the FILE object addressed by f .

RETURN VALUE

fputc returns the character written or EOF if an error occurs.

IMPLEMENTATION

fputc is implemented as an actual function call, not a built-in function, so it is slower than putc . (However, less code is generated.)

EXAMPLE

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

main()
{
   int c;               /* must be int not char  */
   char filename[60];
   FILE *infile, *outfile;

   puts("Enter the name of your input file:");
   memcpy(filename, "tso:", 4);
   gets(filename+4);
   infile = fopen(filename, "r");
   if (!infile){
      puts("Failed to open input file.");
      exit(EXIT_FAILURE);
   }
   puts("Enter the name of your output file:");
   memcpy(filename, "tso:", 4);
   gets(filename+4);
   outfile = fopen(filename, "w");
   if (!outfile){
      puts("Failed to open output file.");
      exit(EXIT_FAILURE);
   }

      /* Read characters from file MYFILE.       */
   while ((c = fgetc(infile)) != EOF)
         /* Write characters to YOURFILE.        */
      if (fputc(c, outfile) == EOF) break;
   fclose(infile);
}
