NOTE TO DEVELOPERS
|
|
|
|
The routines you write here must work closely with fixincl.c.
|
|
|
|
Here are the rules:
|
|
|
|
1. Every test procedure name must be suffixed with "_test".
|
|
These routines will be referenced from inclhack.def, sans the suffix.
|
|
|
|
2. Use the "TEST_FOR_FIX_PROC_HEAD()" macro _with_ the "_test" suffix
|
|
(I cannot use the ## magic from ANSI C) for defining your entry point.
|
|
|
|
3. Put your test name into the FIX_TEST_TABLE
|
|
|
|
4. Do not write anything to stdout. It may be closed.
|
|
|
|
5. Write to stderr only in the event of a reportable error
|
|
In such an event, call "exit(1)".
|
