// (in X windows, you're supposed to call Xfree for example), in the platform
|

|

// "new Bit8u[length]". Then the pointer is passed into
|
|
// bx_keyb_c::paste_bytes, along with the length. The gui code never touches
|
|
// the pastebuf again, and does not free it. The keyboard code is
|
|
// responsible for deallocating the paste buffer using delete [] buf. The
|
|
// paste buffer is binary data, and it is probably NOT null terminated.
