Hi Phil, end of July last year, Alexandre Raczynski asked about accessing QSharedMemory, and you replied, that:
mutable_data = buffer(sharedMemory.data()) ...should give _write_ access to the memory. Hmm, not here: $ python Python 2.6 (r26:66714, Mar 30 2010, 00:30:21) [GCC 4.3.2 [gcc-4_3-branch revision 141291]] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from PyQt4 import QtCore >>> >>> shmem = QtCore.QSharedMemory("xxx") >>> shmem.create(10) True >>> shmem.lock() True >>> b = buffer(shmem.data()) >>> repr(b) '<read-only buffer for 0xb74a37a0, size -1, offset 0 at 0xb6c0f9a0>' >>> b = buffer(shmem.data(), 0, 10) >>> repr(b) '<read-only buffer for 0xb74a3710, size 10, offset 0 at 0xb6c0f9c0>' >>> Both attempts to create a buffer object resulted in read-only buffers, that refuse getting modified. I must be doing something wrong, but there's not much room left for manoeuvring..
