open_config_buffer Subroutine

public subroutine open_config_buffer(L, buffer, bufName, ErrCode, ErrString)

Subroutine to load and execute a script given in a buffer (bytecode).

Arguments

Type IntentOptional Attributes Name
type(flu_State) :: L

Handle to the Lua script
character(len=1), intent(in) :: buffer(:)

String with Lua code to load.
character(len=*), intent(in), optional :: bufName

Name for the buffer to use in debug messages.
integer, intent(out), optional :: ErrCode

Error code returned by Lua during loading or executing the file.

This optional parameter might be used to react on errors in the calling side. If neither ErrCode nor ErrString are given, this subroutine will stop the program execution and print the error message from Lua to the stdout.
character(len=*), intent(out), optional :: ErrString

Obtained error description from the Lua stack.

This optional argument holds the Lua error message in case somehting went wrong. It can be used to provide some feedback to the user in the calling routine. If neither ErrCode nor ErrString are provided, open_config() will print the error message and stop program execution.
