!!DESCRIPTION |

|
| |
|
21 |
__ifnames__ can help when writing a __configure.ac__ |
| |
|
22 |
for a software package. It prints the identifiers that the |
| |
|
23 |
package already uses in C preprocessor conditionals. If a |
| |
|
24 |
package has already been set up to have some portability, |
| |
|
25 |
this program can help you figure out what its |
| |
|
26 |
__configure__ needs to check for. It may help fill in |
| |
|
27 |
some gaps in a __configure.ac__ generated by |
| |
|
28 |
__autoscan__ (see autoscan(1)). |
| |
|
29 |
|
| |
|
30 |
|
| |
|
31 |
__ifnames__ scans all of the C source files named on the |
| |
|
32 |
command line (or the standard input, if none are given) and |
| |
|
33 |
writes to the standard output a sorted list of all the |
| |
|
34 |
identifiers that appear in those files in __#if__, |
| |
|
35 |
__#elif__, __#ifdef__, or __#ifndef__ directives. |
| |
|
36 |
It prints each identifier on a line, followed by a |
| |
|
37 |
space-separated list of the files in which that identifier |
| |
|
38 |
occurs. |
| |
|
39 |
|

__ifnames__ accepts the following options: |
