char *fgets(char *s, size_t n, FILE *stream);
Points to a buffer that is to hold the characters read.
Is the size, in bytes, of the buffer pointed to by s.
Is the stream from which the characters are read.
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, not 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.
MULTITHREAD SAFETY LEVEL
For files opened in text-mode, the character sequence carriage-return linefeed is translated into linefeed. No such translation occurs for files opened in binary mode.
