int read(int fildes, char *buf, int count);

Parameters for this facility are:

fildes	int	The file descriptor
buf	char *	A buffer to store the data read
count	int	The maximum size in bytes to read

The function read() copies the number of bytes specified by the count argument, from the file to the character buffer. File reading begins at the current position. The position moves to the end of the read position when the operation is completed.

read() returns the number of bytes actually read from the file. In case of an error a value of negative one is returned and errno is set.
