[Qemu-devel] [PATCH] Fix conversions from pointer to int and vice versa |
Date: |
Wed, 23 Feb 2011 19:09:16 +0100 |
Here the int values fds[0], sigfd, s, sock and fd are converted
to void pointers which are later converted back to an int value.
These conversions should always use intptr_t instead of unsigned long.
They are needed for environments where sizeof(long) != sizeof(void *).
