aot_err_module Module

This module provides the handling of errors.

The aoterr_* constants are used to identify specific kinds of errors that might appear when attempting to obtain a value from the Lua script.

The aot_err_handler provides access to error messages that might be issued by Lua itself for routines in the Lua API that return an error code.

Variables

Type Visibility Attributes Name Initial
integer, public, parameter :: aoterr_Fatal = 0

Indication of a a fatal error if this bit is set in an error code.
integer, public, parameter :: aoterr_NonExistent = 1

Indication that the requested value does not exist in the Lua script if this bit is set in an error code.
integer, public, parameter :: aoterr_WrongType = 2

Indication that a requested value exists in the Lua script but has the wrong data type.

Subroutines

Arguments

Type IntentOptional Attributes Name
type(flu_State) :: L

Handle to the Lua script
integer, intent(in) :: err

Lua error code to evaluate
character(len=*), intent(in) :: msg

Some additional message that should be prepended to the Lua error message if the program is stopped by the handler (no ErrString or ErrCode provided).
character(len=*), intent(out), optional :: ErrString

Resulting error string obtained by combining msg and the error description on the Lua stack.
integer, intent(out), optional :: ErrCode

The Lua error code, just the same as err.
