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