11 NOTE TO DEVELOPERS
|
|
|
12
|
|
|
13 The routines you write here must work closely with fixincl.c.
|
|
|
14
|
|
|
15 Here are the rules:
|
|
|
16
|
|
|
17 1. Every test procedure name must be suffixed with "_fix".
|
|
|
18 These routines will be referenced from inclhack.def, sans the suffix.
|
|
|
19
|
|
|
20 2. Use the "FIX_PROC_HEAD()" macro _with_ the "_fix" suffix
|
|
|
21 (I cannot use the ## magic from ANSI C) for defining your entry point.
|
|
|
22
|
|
|
23 3. Put your test name into the FIXUP_TABLE.
|
|
|
24
|
|
|
25 4. Do not read anything from stdin. It is closed.
|
|
|
26
|
|
|
27 5. Write to stderr only in the event of a reportable error
|
|
|
28 In such an event, call "exit (EXIT_FAILURE)".
|
|
|
29
|
|
|
30 6. You have access to the fixDescList entry for the fix in question.
|
|
|
31 This may be useful, for example, if there are interesting strings
|
|
|
32 or pre-compiled regular expressions stored there.
