GetModuleInformation function (psapi.h)
Retrieves information about the specified module in the MODULEINFO structure.
Syntax
BOOL GetModuleInformation(
[in] HANDLE hProcess,
[in] HMODULE hModule,
[out] LPMODULEINFO lpmodinfo,
[in] DWORD cb
);
Parameters
[in] hProcess
A handle to the process that contains the module.
The handle must have the PROCESS_QUERY_INFORMATION and PROCESS_VM_READ access rights. For more information, see Process Security and Access Rights.
[in] hModule
A handle to the module.
[out] lpmodinfo
A pointer to the MODULEINFO structure that receives information about the module.
[in] cb
The size of the MODULEINFO structure, in bytes.
Return value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
To get information for the calling process, pass the handle returned by GetCurrentProcess.
The GetModuleInformation function does not retrieve information for modules that were loaded with the LOAD_LIBRARY_AS_DATAFILE flag. For more information, see LoadLibraryEx.
Starting with Windows 7 and Windows Server 2008 R2, Psapi.h establishes version numbers for the PSAPI functions. The PSAPI version number affects the name used to call the function and the library that a program must load.
If PSAPI_VERSION is 2 or greater, this function is defined as K32GetModuleInformation in Psapi.h and exported in Kernel32.lib and Kernel32.dll. If PSAPI_VERSION is 1, this function is defined as K32GetModuleInformation in Psapi.h and exported in Psapi.lib and Psapi.dll as a wrapper that calls K32GetModuleInformation.
Programs that must run on earlier versions of Windows as well as Windows 7 and later versions should always call this function as K32GetModuleInformation. To ensure correct resolution of symbols, add Psapi.lib to the TARGETLIBS macro and compile the program with -DPSAPI_VERSION=1. To use run-time dynamic linking, load Psapi.dll.
