/* 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. However, when compiling for Virtual Pascal, things are done
|
|
differently, and global variables are not used (see pcre.in). */
