Title: CMem
| Old | New | Line | |
|---|---|---|---|
| 1 | + | If you include the **cmem** unit in your uses clause of your program, it will replace the native Free Pascal memory manager with the C library memory manager. All memory management is then done by the C memory manager. | |
| 2 | + | ||
| 3 | + | The unit should be the first unit in the uses clause, otherwise memory can already be allocated by initialization routines in units that are initialized before the C memory manager is installed. | |
| 4 | + | ||
| 5 | + | In cases where several units like **cthreads** , **cmem** and **cwstrings** are recommended to be placed first, due to how the units work a sensible order is | |
| 6 | + | ||
| 7 | + | * cmem | |
| 8 | + | * cthreads | |
| 9 | + | * cwstrings | |
| 10 | + | ||
| 11 | + | There is a small example program [**testcmem**](<https://gitlab.com/freepascal.org/fpc/source/-/blob/release_3_2_2/tests/test/testcmem.pp>), which demonstrates the use of the cmem unit. | |
| 12 | + | ||
| 13 | + | CMem should not be used if [[heaptrc]] is used. | |
