The following describes the most significant changes which occurred in the AST library between versions V5.5-0 and V5.6-0:
grf.h
. The ast_link command has been modified so
that the -grf_v3.2
switch loads dummy versions of the new grf
functions. This means that applications that use the -grf_v3.2
switch should continue to build without any change. However, the new public
routines AST_BBUF and AST_EBUF
will report an error unless the new grf functions are implemented. If you
choose to implement them, you should modify your linking procedure to
use the -grf
(or -grf_v5.6
) switch in place of the older
-grf_v3.2
switch. See the description of the ast_link command for
details of these switches.
