This looks fine although based on experience I'd tend to write it as...
#ifdef HAVE_OPEN_MEMSTREAM
if (fout)
#endif
{
/* Testing EBADF special-cases >&- redirections */
if ((fout != stdout) ? (fclose(fout) != 0) :
(fflush(fout) != 0 && errno != EBADF)) {
zwarnnam(name, "write error: %e", errno);
ret = 1;
}
}
for clarity. The braces are harmless without HAVE_OPEN_MEMSTREAM and
explain the indentation --- otherwise you may well find lint or Coverity
wailing they don't understand the indentation.
(... anyone remember lint ...?)
