Declaration:
int getc(FILE * stream);
Gets the next character (an unsigned char )
from the specified stream and advances the position indicator
for the stream.
This may be a macro version of fgetc .
On success the character is returned. If the end-of-file is
encountered, then EOF is returned and the
end-of-file indicator is set. If an error occurs then the error
indicator for the stream is set and EOF is
returned.
