41 | /* This module contains global variables that are exported by the PCRE library. |
42 | PCRE is thread-clean and doesn't use any global variables in the normal sense. |
43 | However, it calls memory allocation and freeing functions via the four |
44 | indirections below, and it can optionally do callouts, using the fifth |
45 | indirection. These values can be changed by the caller, but are shared between |
46 | all threads. |
47 | |
48 | For MS Visual Studio and Symbian OS, there are problems in initializing these |
49 | variables to non-local functions. In these cases, therefore, an indirection via |
50 | a local function is used. |
51 | |
52 | Also, when compiling for Virtual Pascal, things are done differently, and |
53 | global variables are not used. */ |
