41/* This module contains global variables that are exported by the PCRE library.
42PCRE is thread-clean and doesn't use any global variables in the normal sense.
43However, it calls memory allocation and freeing functions via the four
44indirections below, and it can optionally do callouts, using the fifth
45indirection. These values can be changed by the caller, but are shared between
46all threads. However, when compiling for Virtual Pascal, things are done
47differently, and global variables are not used (see pcre.in). */
