rundll32 is a command line accessible interface for calling functions in a DLL. Note that this only works with DLLs that export functions designed for use with rundll32.
Usage
wine rundll32 <dll_file>,<function> [function arguments]
dll_file is the file name of the binary to be loaded. Note that <dll_file>,<function> cannot contain spaces, quotation marks, or another comma. (It may be useful to use winepath to get the short file name and path.)
function is the name of the function in dll_file to be called.
function arguments are parameters to be passed to the DLL function as a string.
