read

Description:

[ CCode ( cname = "fread" , instance_pos = -1 ) ]
public size_t read (uint8[] buf, size_t size = 1)

Reads specified number of objects in the array buffer from the given input stream stream.

Example: Read n bytes:

public static int main (string[] args) {
	// open file stream:
	FileStream stream = FileStream.open ("GLib.FileStream.read.vala", "r");
	assert (stream != null);

	// get file size:
	stream.seek (0, FileSeek.END);
	long size = stream.tell ();
	stream.rewind ();

	// load content:
	uint8[] buf = new uint8[size];
	size_t read = stream.read (buf);
	assert (size == read);

	// display content:
	print ((string) buf);	

	return 0;
}

valac --pkg glib-2.0 GLib.FileStream.read.vala

Parameters:

buf	pointer to the first object object in the array to be read
size	the element's size, this is always sizeof(uint8) or 1

Returns:

number of objects read successfully
