This function allows you to read data from a file, without encoding and line terminators
Name | Description |
---|---|
File:handle | File handle to use, opened by fopen() |
buffer | The buffer to save the read data in. |
size = sizeof (buffer) | The number of cells to read. |
Returns
The number of cells read. Zero, if the file end has been reached.
Examples
// 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_read);
// Declare "file_len"
new 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 larger than the array
if (file_len == (some_enum*4))
{
// Success
// Read from "file.bin" into "some_data"
fblockread(handle, some_data);
}
else
{
// Error
