Function Documentation

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.

void acpi_Shutdown

(

)

invalidates all pointers returned by acpi_GetTable.
