SymLoadModule

IN HANDLE hProcess,

IN HANDLE hFile,

IN LPSTR ImageName,

IN LPSTR ModuleName,

IN DWORD BaseOfDll,

IN DWORD SizeOfDll

);

Parameters
hProcess

The process handle that was originally passed to SymInitialize.

hFile

The file handle for the executable image. This argument is used mostly by debuggers, where the debugger passes the file handle obtained from a debug event. A value of NULL indicates that the hFile is not used.

ImageName

The name of the executable image. This name can contain a partial path, a full path, or no path at all. If the file cannot be located by the name provided, the symbol search path is used.

ModuleName
A shortcut name for the module. If the pointer value is NULL, IMAGEHLP creates a name using the base name of the symbol file.

BaseOfDll

The load address of the module. If the value is zero, IMAGEHLP obtains the load address from the symbol file. The load address contained in the symbol file is not necessarily the actual load address. Debuggers and other applications having an actual load address should use the real load address when calling this function.

SizeOfDll

The size of the module. If the value is zero, IMAGEHLP obtains the size from the symbol file. The size contained in the symbol file is not necessarily the actual size. Debuggers and other applications having an actual size should use the real size when calling this function.

Return Values
If the function succeeds, the return value is TRUE.

If the function fails, then the return value is FALSE. To retrieve extended error information, call GetLastError.

Remarks
The symbol handler creates an entry for the module and if the deferred symbol loading option is turned off, an attempt is made to load the symbols. If deferred symbol loading is enabled, the module is marked as deferred and the symbols are not loaded until a reference is made to a symbol in the module.

    Nostalgia .Net     .Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More »
