int getc(FILE *stream);
On failure, errno is set to one of the following values:
Another process has the file locked.
stream is not a valid stream opened for reading.
A signal interrupted the call.
An input error occurred.
The open object is a directory, rather than a file.
Memory could not be allocated for internal buffers.
A device error occurred.
The file is a regular file and an attempt was made to read at or beyond the offset maximum associated with the corresponding stream.
The underlying file descriptor is a non-blocking socket and no data is ready to be read.
If the stream is from a file opened in text mode, the line-terminating character sequence carriage return plus linefeed is translated to linefeed. No such translation occurs for files opened in binary mode.
