# HICON\_UserSize(3w)

## NAME

**HICON\_UserSize** (OLE32.@)

## SYNOPSIS

ULONG \_\_RPC\_USER  HICON\_UserSize\
  (\
   ULONG\* *pFlags*,\
   ULONG  *StartingSize*,\
   HICON\* *phIcon*\
  )

## DESCRIPTION

Calculates the buffer size required to marshal an icon.

## PARAMS

*pFlags* **\[In\]**  Flags. See notes.

*StartingSize* **\[In\]**  Starting size of the buffer. This value is added on to the buffer size required for the icon.

*phIcon* **\[In\]**  Icon to size.

## RETURNS

The buffer size required to marshal an icon plus the starting size.

## NOTES

Even though the function is documented to take a pointer to a **ULONG** in *pFlags*, it actually takes a pointer to a **USER\_MARSHAL\_CB** structure, of which the first parameter is a **ULONG**. This function is only intended to be called by the **RPC** runtime.

## IMPLEMENTATION

Declared in **"shobjidl.h"**.

Implemented in **"dlls/ole32/usrmarshal.c"**.

Debug channel **"ole"**.
