1 | Conformance of the GNU libc with various standards |
| 2 | ================================================== | |
| 3 | ||
| 4 | The GNU libc is designed to be conformant with existing standard as | |
| 6a3b5b5c | 5 | far as possible. To ensure this I've run various tests. The results |
| 107f8131 UD |
6 | are presented here. |

| 9 | Open Group's hdrchk | |
| 10 | ------------------- | |
| 11 | ||
| 12 | The hdrchk test suite is available from the Open Group at | |
| 13 | ||
| 14 | ftp://ftp.rdg.opengroup.org/pub/unsupported/stdtools/hdrchk/ | |
| 15 | ||
| 16 | I've last run the suite on 1998-07-08 on a Linux/ix86 system with the | |
| 17 | following results [*]: | |
| 18 | ||
| 19 | FIPS No reported problems | |
| 20 | ||
| 21 | POSIX90 No reported problems | |
| 22 | ||
| 23 | XPG3 No reported problems | |
| 24 | ||
| 25 | XPG4 The wide character I/O stuff is missing in glibc. | |

| 42 | Beside this a problem in stdio.h is reported but | |
| 43 | this is only because the scripts don't understand | |
| 44 | the sometimes complex constructs in the header. | |
| 45 | ||
| 46 | POSIX96 Same as UNIX98 [see below]. | |
| 47 | UNIX98 Quite a lot of problems, almost all due to limitations | |

| 120 | Only the `wchar.h' problems result from glibc | |
| 121 | defficiencies since we still don't support wide | |
| 122 | character I/O. | |
| 123 | ||
| 124 | [*] Since the scripts are not clever enough for the way gcc handles | |
| 125 | include files (namely, putting some of them in gcc-local directory) I | |
| 126 | copied over the iso646.h, float.h, and stddef.h headers and ignored the | |
| 127 | problems resulting from the splitted limits.h file). |
