Global Variables
----------------
Built-in Global Variables
--------------------------
You can add built-in global variables with qse_awk_addgbl().
Use qse_awk_getgbl() to get information.
QSEAWK predefines global variables such as *SUBSEP* and *ARGC*. You can add
your own built-in variables in the global scope with qse_awk_addgbl(). You
must add new variables before qse_awk_parse() or qse_awk_parsestd(). Later,
you can get the values of the global variables using qse_awk_rtx_getgbl()
with an ID returned by qse_awk_addgbl(). The IDs of the predefined global
variables are available as the ::qse_awk_gbl_id_t type values
\includelineno awk08.c
Built-in Functions
------------------
You can add built-in functions with qse_awk_addfnc().
On the other hand, modular built-in functions reside in a shared object.
QSEAWK predefines built-in functions like *match*. You can add your own
built-in function with qse_awk_addfnc(). The following sample shows how to add
a function named *basename* that get the base file name part of a path name.
\includelineno awk09.c
In the sample above, the *basename* function returns a resulting string. In
case of any implemenation errors, it would cause the runtime context to abort
with an error since it returned -1. To avoid the situation, you may change
the way basename() works by defining it to return the resulting string via
the second parameter and return 0 or -1 as a return value. For the arguements
to pass by reference, you can specify the letter *r* into the *arg.spec* field
at the argument position.
