class EfiVariables
Defined at line 42 of file ../../src/firmware/gigaboot/cpp/efi_variables.h
Helper wrapper class for EFI C API
Contains EFI variables related logic at the moment.
More convenient interface for following functions:
EfiGetNextVariableName()
EfiGetVariable()
QueryVariableInfo()
Provides C++ style container wrapper for VariableName iteration
E.g:
EfiVariables efi_variables;
for (const auto
&
variable_id : efi_variables) {
if (!variable_id.IsValid()) {
return false;
}
// do something with variable_id
}
