s32 Read(
     void * buf,
     size_t size
);

	Name	Description
in	buf	Pointer to the buffer where the data is read into.
in	size	Maximum number of bytes to read.

Returns the actual number of bytes that were copied. If an error occurred, it returns -1.

Reads the specified amount of data from a file into a buffer, and returns the size of data (in bytes) that were actually read.

Up to size bytes of data are read from the current file position and copied to the region at the address specified by buf.
Returns the number of bytes that were copied.

In the debugger environment, the portion in the read buffer after the returned position is undefined.
If there is a difference between the requested size and the read size, do not treat the values beyond the read size as if they were unmodified initialized values.
