Detailed Description
The input_cpio class is used to represent a CPIO archive.
Constructor & Destructor Documentation
| virtual input_cpio::~input_cpio | ( | ) | [virtual] |
The destructor.
| input_cpio::input_cpio | ( | input & | deeper | ) |
The constructor.
- Parameters:
-
deeper The input data source for this filter.
| input_cpio::input_cpio | ( | ) | [private] |
The default constructor. Do not use.
| input_cpio::input_cpio | ( | const input_cpio & | arg | ) | [private] |
The copy constructor. Do not use.
Member Function Documentation
| input input_cpio::child | ( | nstring & | name | ) |
The child method is used to obtain an input which may be read to obtain the data of a member of the CPIO archive.
If there are no more members, a closed input will be returned. Use the input::is_open() method to work this out.
| off_t input_cpio::ftell_inner | ( | ) | [virtual] |
The ftell_inner method is used to determine the unbuffered current position within the input.
Implements input_ty.
| nstring input_cpio::get_name | ( | long | len | ) | [private] |
The get_name method is used to extract the archive name from the deeper input.
- Parameters:
-
len The length of the name, not including the terminating NUL
- Returns:
- a string containing the name
| long input_cpio::hex8 | ( | ) | [private] |
The hex8 method is used to obtain an eight digit hexadecimal number from the input.
| int input_cpio::hex_digit | ( | bool & | arg | ) | [private] |
The hex_digit method is used to obtain a hexadecimal digit from the input.
| bool input_cpio::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.
| off_t input_cpio::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.
| nstring input_cpio::name | ( | ) | [virtual] |
The name method is used to determine the name of the input.
Implements input_ty.
| input_cpio& input_cpio::operator= | ( | const input_cpio & | arg | ) | [private] |
The assignment operator. Do not use.
| void input_cpio::padding | ( | ) | [private] |
The padding method is used advance to the next 4-byte boundary, if necessary.
| ssize_t input_cpio::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.
