- hProcess IntPtr
-
A handle to the process memory to be modified.
The handle must have VirtualMemoryWrite
and VirtualMemoryOperation access to the process.
- baseAddress UIntPtr
-
A pointer to the base address in the specified process to which data is written.
Before data transfer occurs, the system verifies that all data in the
base address and memory of the specified size is accessible for write access,
and if it is not accessible, the function fails.
- buffer IntPtr
-
A pointer to the buffer that contains data to be written in the address space of the specified process.
- size IntPtr
-
The number of bytes to be written to the specified process.
- refNumberOfBytesWritten IntPtr
-
A pointer to a variable that receives the number of bytes transferred into the specified process.
This parameter is optional.
If refNumberOfBytesWritten is Zero, the parameter is ignored.
Boolean
If the function succeeds, the return value is
.
If the function fails, the return value is
.
