SymGetModuleInfo64

SymGetModuleInfo64 is a function provided by the Microsoft Debugging Tools for Windows (Debugging Help Library, DbgHelp.dll) API. It is used to retrieve information about a specific module loaded within a process's address space. This function is the 64-bit version, meaning it is designed for use with 64-bit processes.

The function takes a process handle and a base address of the module as input. It then populates a SYMBOL_INFO structure with details about the module. These details can include the module's name, base address, size, timestamp, and symbolic information if available. The SYMBOL_INFO structure is a key data structure for interacting with symbol information.

SymGetModuleInfo64 is crucial for debugging and diagnostic tools. For instance, it can be used to identify the executable or DLL associated with a particular memory address. This is essential for tasks like resolving stack traces, inspecting memory, and understanding the layout of a running application.

To use SymGetModuleInfo64, a developer typically first obtains a process handle to the target process and then determines the base address of the module of interest. The function call itself involves passing these handles and a pointer to a SYMBOL_INFO structure that will be filled by the function. The success of the operation is indicated by the return value of the function.
