@CAPI[module,function[,integer | PING=n | PLONG=n | PDWORD=n | NULL | BUFFER | "string"] : Returns the result of calling a function with a _cdecl type in a DLL.
module - name of the DLL containing the function
function - function name (case sensitive)
integer - an integer value to pass to the function
PINT - a pointer to the integer n
PLONG - a pointer to the long integer n
PDWORD - a pointer to the DWORD n
NULL - a null pointer (0)
BUFFER - @CAPI will pass an address for an internal buffer for the API to return a Unicode string value.
aBUFFER - @CAPI will pass an address for an internal buffer for the API to return an ASCII string value.
"string" - text argument (this must be enclosed in double quotes). If the argument is preceded by an 'a' (i.e., a"Argument") then it is converted from Unicode to ASCII before calling the API. (Some Windows APIs only accept ASCII arguments.)
@CAPI supports a maximum of 8 arguments. The return value is either a string value returned by the API (if BUFFER or aBUFFER is specified), or the integer value returned by the API. The function must be defined as _cdecl. If @CAPI can't find the specified function, it will append a "W" (for the Unicode version) to the function name and try again.
