The read_inner method is used to read unbuffered data from the given input stream. At most nbytes bytes will be read into data. The number of bytes actually read will be returned. At end-of-file, a value <= 0 will be returned, and data will be unchanged. All file read errors or format errors are fatal, and will cause the method to not return.
- Parameters:
-
data Where to put the results of the read. nbytes The maximum number of bytes to read.
- Returns:
- The actual number of bytes read, or zero for end-of-file.
Implements input_ty.
| long input_null::ftell_inner | ( | ) | [virtual] |
| input_null& input_null::operator= | ( | const input_null & | ) | [private] |
The assignment operator. Do not use.
