MemCopyString Function

Copy one memory buffer to another and fill any remaining spaces with blanks.

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

Syntax

Copy

 FUNCTION MemCopyString(
	ptrDest AS IntPtr,
	cSource AS STRING,
	dwCount AS DWORD
) AS VOID

public static void MemCopyString(
	IntPtr ptrDest,
	string cSource,
	uint dwCount
)

Request Example View Source

Parameters

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

Return Value

Type:

Remarks

MemCopyString() 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.
If the number of bytes in the source memory buffer is less than dwCount, the rest of the destination memory buffer is filled with blanks.
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 MemCopyString():

Copy

1LOCAL pszDest := "Hi there" AS PSZ
2LOCAL pszSrc := "***" AS PSZ
3MemCopyString(pszDest, pszSrc, 5)
4? pszDest                            // "***  ere"
