fgetc
[get a character from a file or stream]

SYNOPSIS
#include <stdio.h>
int fgetc(FILE *fp);

DESCRIPTION
Use fgetc to get the next single character from the file or stream identified by fp. As a side effect, fgetc advances the file’s current position indicator.

For a macro version of this function, see getc.

RETURNS
The next character (read as an unsigned char, and cast to int), unless there is no more data, or the host system reports a read error; in either of these situations, fgetc returns EOF.

You can distinguish the two situations that cause an EOF result by using the ferror and feof functions.

COMPLIANCE
ANSI C requires fgetc.

Supporting OS subroutines required: close, fstat, isatty, lseek, read, sbrk, write.
