Can someone please help me on how to write this in Nim from c?
struct **MC_HMCALLSCRIPTFUNCW** :
Type | Name | Description
---|---|---
UINT | cbSize | Set to sizeof(MC_HMCALLSCRIPTFUNCW)
LPWSTR | pszRet | Set to address of a buffer to store string result of the
function call, or to NULL if the expected return value is of integer type or
there is no return value.
int| iRet | If pszRet is not NULL, set to size of the buffer. If pszRet is NULL
and the function returns integer, it is stored here.
UINT | cArgs Set| to number of arguments passed to the function. (Four at
most.)
LPCWSTR| pszArg1| Specify 1st argument (if it is of string type).
int| iArg1 | Specify 1st argument (if it is of integer type). Ignored if
pszArg1 is not NULL.
LPCWSTR| pszArg2| Specify 2nd argument (if it is of string type).
int| iArg2 | Specify 2nd argument (if it is of integer type). Ignored if
pszArg2 is not NULL.
LPCWSTR| pszArg3| Specify 3rd argument (if it is of string type).
int| iArg3 | Specify 3rd argument (if it is of integer type). Ignored if
pszArg3 is not NULL.
LPCWSTR| pszArg4| Specify 4th argument (if it is of string type).
int| iArg4 | Specify 4th argument (if it is of integer type). Ignored if
pszArg4 is not NULL.
