`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.
*Portability*
ANSI C requires `fgetc'.
   Supporting OS subroutines required: `close', `fstat', `isatty',
`lseek', `read', `sbrk', `write'.
