FGetC -- Read a character from the specified input (buffered) (V36)
char = FGetC(fh)
D0 D1
LONG FGetC(BPTR)
Reads the next character from the input stream. A -1 is
returned when EOF or an error is encountered. This call is buffered.
Use Flush() between buffered and unbuffered I/O on a filehandle.
fh - filehandle to use for buffered I/O
char - character read (0-255) or -1
In V36, after an EOF was read, EOF would always be returned from
FGetC() from then on. Starting in V37, it tries to read from the
handler again each time (unless UnGetC(fh,-1) was called).
