int | version |
unsigned int | refcount |
Reference count for the data source. | |
int(* | open )(IsoDataSource *src) |
Opens the given source. | |
int(* | close )(IsoDataSource *src) |
Close a given source, freeing all system resources previously grabbed in open(). | |
int(* | read_block )(IsoDataSource *src, uint32_t lba, uint8_t *buffer) |
Read an arbitrary block (2048 bytes) of data from the source. | |
void(* | free_data )(IsoDataSource *src) |
Clean up the source specific data. | |
void * | data |
Source specific data. |
It offers homogeneous read access to arbitrary blocks to different sources for images, such as .iso files, CD/DVD drives, etc...
To create a multisession image, libisofs needs a IsoDataSource, that the user must provide. The function iso_data_source_new_from_file() constructs an IsoDataSource that uses POSIX I/O functions to access data. You can use it with regular .iso images, and also with block devices that represent a drive.

Clean up the source specific data. Never call this directly, it is automatically called by iso_data_source_unref() when refcount reach 0. |
|
Opens the given source. You must open() the source before any attempt to read data from it. The open is the right place for grabbing the underlying resources.

Reference count for the data source. Should be 1 when a new source is created. Don't access it directly, but with iso_data_source_ref() and iso_data_source_unref() functions. Definition at line 403 of file libisofs.h. |
