Member Function Documentation
| nstring input_gunzip::name |
( |
|
) |
[virtual] |
The name method is used to determine the name of the input.
Implements input_ty.
| long input_gunzip::length |
( |
|
) |
[virtual] |
The length method is used to determine the length of the input. May return -1 if the length is unknown.
Implements input_ty.
| void input_gunzip::keepalive |
( |
|
) |
[virtual] |
The keepalive method is used to set the SO_KEEPALIVE socket option, if the file is a socket. Does nothing otherwise.
Reimplemented from input_ty.
| long input_gunzip::read_inner |
( |
void * |
data, |
|
|
size_t |
nbytes | |
|
) |
| | [virtual] |
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_gunzip::ftell_inner |
( |
|
) |
[virtual] |
The ftell_inner method is used to determine the unbuffered current position within the input.
Implements input_ty.
| bool input_gunzip::is_remote |
( |
|
) |
const [virtual] |
The is_remote method is used to determine whether or not an input stream is from a local file or a remote source. This is only intended to be a generally informative thing, to provide information to the user, it isn't (and can't be) utterly precise.
Reimplemented from input_ty.
| static bool input_gunzip::candidate |
( |
input & |
deeper |
) |
[static] |
The candidate class method is used to check the magi number of a gzipped file. All of the bytes read are unread before this method returns.
