A similar situation exists with ttyname_r and a few other functions on
Solaris. The default declaration of this function on Solaris is different
from the one specified in POSIX. This leads to:
test-ttyname_r.c:22: warning: initialization from incompatible pointer type
test-ttyname_r.c: In function 'main':
test-ttyname_r.c:45: warning: comparison between pointer and integer
...
test-ttyname_r.c:45: assertion failed
bash: line 5: 20285 Abort (core dumped) EXEEXT=''
srcdir='.' ${dir}$tst
FAIL: test-ttyname_r
The manual pages on Solaris say that in order to get the POSIX compliant
*_r function prototypes, one needs to define _POSIX_PTHREAD_SEMANTICS.
Should we define _POSIX_PTHREAD_SEMANTICS?
Should we document in the INSTALL file that on Solaris, _POSIX_PTHREAD_SEMANTICS
should be defined? (Like we do for _XOPEN_SOURCE on HP-UX.)
In any case, I'm updating the documentation:
2010-04-25 Bruno Haible <br...@clisp.org>
Mention effects of _POSIX_PTHREAD_SEMANTICS on Solaris.
* doc/posix-functions/asctime_r.texi: Mention the Solaris problem.
