System.Runtime.InteropServices.Marshal.WriteInt32 Method

Writes a 32-bit signed integer value to unmanaged memory at a specified offset.

Syntax

[System.Security.SuppressUnmanagedCodeSecurity]
public static void WriteInt32 (object ptr, int ofs, int val)

Parameters

ptr
The base address in unmanaged memory of the target object.
ofs
An additional byte offset, which is added to the ptr parameter before writing.
val
The value to write.

Remarks

Marshal.WriteInt32(IntPtr, int, int) enables direct interaction with an unmanaged 32-bit signed array, eliminating the expense of copying an entire unmanaged array (using Marshal.Copy(Int32[], int, IntPtr, int)) to a separate managed array before setting its element values.

Writing to unaligned memory locations is supported.
