When you create your DLL using "DLL_PROCESS_ATTACH", etc, this is! your
DLLMain() function, though some call it LibMain(), or whatever...
...and the function's first parameter can be used to call
GetModuleFileName(), I'd guess.
This might be another round-about way... as an example.

include dll.e
include machine.e
include misc.e
constant
 k32=open_dll("kernel32.dll")
,GetModuleFileName=define_c_func(k32,"GetModuleFileNameA",{C_UINT,C_POINTER,
C_INT},C_UINT)
atom path, ret
sequence name
path=allocate(256+266)
ret=c_func(GetModuleFileName,{k32,path,256+266})
name=peek({path,ret})
printf(1,"%s\n",{name})
sleep(3)
