Push a character back into a read filehandle. If you've read a character from that file you may always push at least 1 character back. UnGetC(file,-1) ungets the last character read. This also works for EOF.
INPUTS
file
Filehandle you've read from.
character
Character to push back or EOF.
RESULT
!=0 if all went well, 0 if the character couldn't be pushed back. IoErr() gives additional information in that case.
