VM write

Virtual Memory

Below are functions used to write data into a target process. Note that these functions can only succeed if the address that is being written at resides in a page that has writable protection set.

Writing Integral Types

• vm.writeInt8(memoryAddress, value)
• vm.writeUInt8(memoryAddress, value)
• vm.writeInt16(memoryAddress, value)
• vm.writeUInt16(memoryAddress, value)
• vm.writeInt32(memoryAddress, value)
• vm.writeUInt32(memoryAddress, value)
• vm.writeInt64(memoryAddress, value)
• vm.writeUInt64(memoryAddress, value)
• vm.writePointer(memoryAddress, value)

Writes an integer or pointer value at memoryAddress. 'U' means Unsigned.

Raises bitslicer.VirtualMemoryError if unable to write the number of required bytes at memoryAddress.

Writing Fractional Types

• vm.writeFloat(memoryAddress, value)
• vm.writeDouble(memoryAddress, value)

Writes a float or double value to memoryAddress

Raises bitslicer.VirtualMemoryError if unable to write the number of required bytes at memoryAddress.

Writing String Types

• vm.writeString8(memoryAddress, buffer)
• vm.writeString16(memoryAddress, buffer)

Writes the contents of buffer (which can be a string or bytes object) plus a 8 or 16 bit NULL terminating byte at memoryAddress.

Raises bitslicer.VirtualMemoryError if unable to write the number of required bytes at memoryAddress or raises a BufferError if unable to parse the buffer.

Writing Bytes

• vm.writeBytes(memoryAddress, buffer)

vm.writeBytes writes a contiguous buffer into memoryAddress.

vm.writeBytes raises bitslicer.VirtualMemoryError if unable to write buffer at memoryAddress or raises a BufferError if unable to parse the buffer.

Note: If you are reading and writing instructions, use debug.writeBytes instead.
