public subroutine aot_err_handler(L, err, msg, ErrString, ErrCode)

Error handler to capture Lua errors.

This routine encapsulates the retrieval of error messages from the Lua stack upon a failing Lua operation. It should be be used after all flu functions that return an err argument as result. Examples are fluL_loadfile and flu_pcall. The ErrString and ErrCode parameters are both optional. If none of them are provided, the execution will be stopped if an error had occured and err is not 0. The error message will be written to standard output in this case.

If either of them is provided, the application will continue and the calling side has to deal with the occured error.

Arguments

TypeIntentOptionalAttributesName
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.
