Typedef Documentation

PCV_AcpiTable

typedef const volatile AcpiTable* PCV_AcpiTable

PCV_u8

typedef const volatile u8* PCV_u8

Function Documentation

acpi_GetTable()

const AcpiTable * acpi_GetTable

(

const char *

signature

)

Parameters

signature

e.g. "RSDT"

Returns

pointer to internal storage (valid until acpi_Shutdown())

note: the first call may be slow, e.g. if a kernel-mode driver is loaded. subsequent requests will be faster since tables are cached.

acpi_Shutdown()

void acpi_Shutdown

(

)

invalidates all pointers returned by acpi_GetTable.
