nn::fs::FileStream::Read Member Function

virtual s32 Read(
     void * buffer,
     size_t size
);

	Name	Description
in	buffer	Pointer to the buffer where the data will be copied.
in	size	Maximum number of bytes to copy.

Returns the actual number of bytes that were copied. Returns 0 if it reached the end of the file.

Loads the specified amount of data from a file into a buffer.

Up to size bytes of data are read from the current file position and copied to the region at the address specified by buffer.

This function is implemented to show an error screen when errors occur internally, whether or not such errors are fatal. Control does not return from the function in this case. Use nn::fs::FileStream::TryRead on everything other than ROM archives.
