00041 /* This module contains global variables that are exported by the PCRE library.
00042 PCRE is thread-clean and doesn't use any global variables in the normal sense.
00043 However, it calls memory allocation and freeing functions via the four
00044 indirections below, and it can optionally do callouts, using the fifth
00045 indirection. These values can be changed by the caller, but are shared between
00046 all threads.
00047 
00048 For MS Visual Studio and Symbian OS, there are problems in initializing these
00049 variables to non-local functions. In these cases, therefore, an indirection via
00050 a local function is used.
00051 
00052 Also, when compiling for Virtual Pascal, things are done differently, and
00053 global variables are not used. */
