1 | (1) Make implementation changes necessary to allow multiple processes |
2 | to use the mmalloc managed region simultaneously. This requires, | |
3 | at the minimum, some sort of cooperative locking that ensures that | |
4 | only one process at a time is changing any of the mmalloc managed | |
5 | data structures (its ok for the mmalloc managed data regions to be | |
6 | changed at any time since we don't care about their contents). | |
7 | ||
8 | (2) In order to support multiple processes using the mmalloc managed | |
9 | region, the malloc descriptor needs to be broken into two parts, | |
10 | one part which is specific to the given process and is maintained | |
11 | separately on a per process basis, and another part which is common | |
12 | to all processes. As an example, the file descriptor is specific | |
13 | to a given process, as are the morecore and abortfunc pointers. | |
14 | However magic[], the version number, the flags field, etc are | |
15 | common to all processes. |
