Summary

Writes the data of an exported variable.

Pascal

 function WriteModuleData(Module: TModuleHandle; SymbolName: string; var Buffer; Size: Cardinal): Boolean;

Parameters

Parameters	Description
Module: TModuleHandle	Handle to the loaded module.
SymbolName: string	Name of the exported variable to access.
var Buffer	The untyped source of the copy.
Size: Cardinal	Amount of bytes to copy.

Description

WriteModuleData copies the contents of Buffer to the exported variable SymbolName. Size tells the amount of bytes to be copied. This function allows to set variables in dynamic modules which are not directly accessible in Pascal. BEWARE! You are accessing the DLL memory image directly. Be sure to access a variable not a function and be sure to write the correct amount of data. The changes are not persistent. They get lost when the DLL is unloaded.
