fgetc

#include <stdio.h>

int fgetc (
  FILE *stream);    /* stream to read from */

The fgetc function reads a single character from stream and updates the file pointer to point to the next character.

The fgetc function is in the RL-FlashFS library. The prototype is defined in stdio.h.

The fgetc function returns the character read as an int type. An EOF is returned for error or end-of-file conditions.

Use the feof or ferror functions to distinguish an error from end-of-file.

void tst_fgetc (void) {
   FILE *fin;
   int ch;

   fin = fopen ("Test.txt","r");
   if (fin == NULL) {
      printf ("File not found!\n");
   }
   else {
      // dump the text file to a screen
      while ((ch = fgetc (fin)) != EOF) {
         putchar (ch);
      }
      fclose (fin);
   }
