MemCopy Function

Copy one memory buffer to another.

Namespace: XSharp.RT
Assembly: XSharp.RT (in XSharp.RT.dll) Version: 2.19

Syntax

Copy

 FUNCTION MemCopy(
	ptrDest AS IntPtr,
	ptrSource AS IntPtr,
	dwCount AS DWORD
) AS IntPtr

public static IntPtr MemCopy(
	IntPtr ptrDest,
	IntPtr ptrSource,
	uint dwCount
)

Request Example View Source

Parameters

ptrDest: Type: IntPtr
A pointer to the destination memory buffer.
ptrSource: Type: IntPtr
A pointer to the source string to copy.
dwCount: Type: DWord
The number of bytes to copy.

Return Value

Type: IntPtr
A pointer to the destination memory buffer.

Remarks

MemCopy() copies the specified number of bytes from the source memory buffer to the destination memory buffer.
If portions of memory occupied by the source string overlap with portions in the destination, the overlapping region is overwritten.
Use MemMove() to copy overlapping regions before they are overwritten.

Tip
This function allows the direct manipulation of a memory location and should be used with extreme care.

Examples

This example uses MemCopy():

Copy

1LOCAL pszDest := "Hi there" AS PSZ
2LOCAL pszSrc := "***" AS PSZ
3MemCopy(pszDest, pszSrc, 3)
4? pszDest                            // ***there
