Warning

Using an invalid handle will crash your server! Get a valid handle by using fopen or ftemp.


Example Usage:

// Define "some_enum"
enum _:some_enum
{
	some_data1,
	some_data2[20],
	Float:some_data3
}
 
// Declare "some_data"
new some_data[some_enum];
 
// ...
 
// Open "file.bin" in "read only" mode
new File:handle = fopen("file.bin", io_write)
 
	// Declare "file_len"
	file_len;
 
// Check, if "file.bin" is open
if(handle)
{
	// Success
 
	// Get the file length of "file.bin"
	file_len = flength(handle);
 
	// If file is equally large than the array
	if(file_len == (some_enum*4))
	{
		// Success
 
		// Read from "file.bin" into "some_data"
		fblockread(handle, some_data);
	}
	else
	{
		// Error
		print("\"file.bin\" is not compatible with the array.");
	}
 
	// Close "file.bin"
	fclose(handle);
