Member Function Documentation

bool ata_device::ata_cmd_is_ok ( const ata_cmd_in in,
bool  data_out_support = false,
bool  multi_sector_support = false,
bool  ata_48bit_support = false 
)
inlineprotected

Check command input parameters (old version).

Definition at line 527 of file dev_interface.h.

bool ata_device::ata_cmd_is_supported ( const ata_cmd_in in,
unsigned  flags,
const char *  type = 0 
)
protected

Check command input parameters.

Return false if required features are not implemented. Calls set_err(...) accordingly.

Definition at line 142 of file dev_interface.cpp.

bool ata_device::ata_identify_is_cached ( ) const
virtual

Return true if OS caches ATA identify sector.

Default implementation returns false.

Reimplemented in anonymous_namespace{atacmds.cpp}::parsed_ata_device, and os_win32::win_ata_device.

Definition at line 191 of file dev_interface.cpp.

virtual bool ata_device::ata_pass_through ( const ata_cmd_in in,
ata_cmd_out out 
)
pure virtual
bool ata_device::ata_pass_through ( const ata_cmd_in in)

ATA pass through without output registers.

Return false on error. Calls ata_pass_through(in, dummy), cannot be reimplemented.

Definition at line 136 of file dev_interface.cpp.

void ata_device::hide_ata ( bool  hide = true)
inlineprotected

Hide/unhide ATA interface.

Definition at line 540 of file dev_interface.h.
