* Allow strerror(0) and strerror_r(0, ...).Jilles Tjoelker2011-04-051-1/+4
| | | | | | | | | | | | | | | | Of course, strerror_r() may still fail with ERANGE. Although the POSIX specification said this could fail with EINVAL and doing this likely indicates invalid use of errno, most other implementations permitted it, various POSIX testsuites require it to work (matching the older sys_errlist array) and apparently some applications depend on it.

* Rearrange strerror() so that its itoa procedure can be used withMike Barcroft2002-12-181-1/+6
| | | | | | | | | | | | | | | | | | strerror_r(). Doing this allows us to ensure that strerror_r() always fills the supplied buffer regardless of EINVAL or ERANGE errors. strerror()'s semantics have changed slightly such that an argument of 0 is now considered invalid and errno is set to EINVAL. Remove internal regression test for strerror() and strerror_r(). This will be reincarnated in src/tools/regression/lib/libc/string. In strerror(3), add a comment about strerror()'s bogus return type.

* Make strerror and strerror_r use sys_errlist[0] for errnum = 0. BeWes Peters2001-12-071-3/+12
| | | | | | | | | | | | | | more careful about reporting truncation with ERANGE in strerror_r. Set errno to EINVAL for "unknown" errnum in strerror as required by P1003.1-200x Draft June 14, 2001. More carefully document the handling of strerrbuf when errors (ERANGE, EINVAL) are encountered in strerror_r. Reviewed by: bde (ongoing discussion) Notes: svn path=/head/; revision=87480
