fgetc Function

Get a character from a stream

Attention: This function is not implemented by MPLAB XC8 for PIC MCUs. It is implemented by all other compilers, but MPLAB XC8 for AVR MCUs has limited support of data streams.

Include

<stdio.h>

Prototype

int fgetc(FILE * stream);

Argument

stream
pointer to the open stream

Return Value

Returns the character read or EOF if a read error occurs or end-of-file is reached.

Remarks

The function reads the next character from the input stream, advances the file-position indicator and returns the character as an unsigned char converted to an int.

Example

See the notes at the beginning of this chapter or section for information on using printf() or scanf() (and other functions reading and writing the stdin or stdout streams) in the example code.

#include <stdio.h>

int main(void)
{
  FILE *buf;
  char y;

  if ((buf = fopen("afile.txt", "r")) == NULL)
    printf("Cannot open afile.txt\n");
  else
  {
    y = fgetc(buf);
    while (y != EOF)
    {
      printf("%c|", y);
      y = fgetc(buf);
    }
    fclose(buf);
  }
}

Example Input

Contents of afile.txt (used as input):

Short
Longer string

Example Output

S|h|o|r|t|
|L|o|n|g|e|r| |s|t|r|i|n|g|
