    pText As UShort(), _
    <OutAttribute> pSize As SIZE() _
) As Integer

int VsGetTextExtent(
    uint hdc,
    int cch,
    ushort[] pText,
    SIZE[] pSize
)

int VsGetTextExtent(
    [InAttribute] unsigned int hdc, 
    [InAttribute] int cch, 
    [InAttribute] array<unsigned short>^ pText, 
    [OutAttribute] array<SIZE>^ pSize
)

abstract VsGetTextExtent : 
        hdc:uint32 * 
        cch:int * 
        pText:uint16[] * 
        pSize:SIZE[] byref -> int

function VsGetTextExtent(
    hdc : uint, 
    cch : int, 
    pText : ushort[], 
    pSize : SIZE[]
) : int

Parameters

hdc
Type: System.UInt32
[in] Pointer to a long type to a hardware device context (HDC).

cch
Type: System.Int32
[in] Number of characters, or -1 if null-terminated.
