Description

http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=5054112

Fix is attached. Still need review.

[dep, 27May2004]

_tx_error, called by t_error, is supposed to display a message,
  followed by the error string for the error defined in t_errno,
  followed by the error string for the error defined in errno.  If any
  of the system calls/library routines invoked between the start of
  _tx_error and when it calls perror() set errno, the output will be
  incorrect.

This doesn't look right to me. You're looking up t_strerror of the old errno, and then printing out the user-supplied string again anyway, and the no newline. Surely the lines starting at 58 should be along the lines of
if (local_t_errno == TSYSERR) {
(void) write(2, ": ", 2);
c = strerror(local_errno);
n = strlen(c);
(void) write(2, c, (unsigned)n);
}
(void) write(2, "\n", 1);
Cheers,
Rob

I've made the minimum changes to resolve the problem noted in this bug report. However, I don't have a way to test this version or to reproduce the problem. Can anyone help with this?
