off_t cdio_lseek | ( | const CdIo_t * | p_cdio, | |
off_t | offset, | |||
int | whence | |||
) |
Reposition read offset Similar to (if not the same as) libc's lseek()
p_cdio | object to get information from | |
offset | amount to seek | |
whence | like corresponding parameter in libc's lseek, e.g. SEEK_SET or SEEK_END. |
ssize_t cdio_read | ( | const CdIo_t * | p_cdio, | |
void * | p_buf, | |||
size_t | i_size | |||
) |
Reads into buf the next size bytes. Similar to (if not the same as) libc's read()
p_cdio | object to read from | |
p_buf | place to read data into. The caller should make sure this location can store at least i_size bytes. | |
i_size | number of bytes to read |
driver_return_code_t cdio_read_audio_sector | ( | const CdIo_t * | p_cdio, | |
void * | p_buf, | |||
lsn_t | i_lsn | |||
) |
Read an audio sector
p_cdio | object to read from | |
p_buf | place to read data into. The caller should make sure this location can store at least CDIO_FRAMESIZE_RAW bytes. | |

uint32_t | i_blocks | |||
) |
Read a data sector
p_cdio | object to read from | |
p_buf | place to read data into. The caller should make sure this location can store at least ISO_BLOCKSIZE, M2RAW_SECTOR_SIZE, or M2F2_SECTOR_SIZE depending on the kind of sector getting read. If you don't know whether you have a Mode 1/2, Form 1/ Form 2/Formless sector best to reserve space for the maximum, M2RAW_SECTOR_SIZE. | |
i_lsn | sector to read | |
i_blocksize | size of block. Should be either CDIO_CD_FRAMESIZE, M2RAW_SECTOR_SIZE, or M2F2_SECTOR_SIZE. See comment above under p_buf. | |
