Jtux Errata
5-Nov-2005

1. In the compilation instructions on the web site, you need a space after "-Wno-unknown-pragmas" and "-I$INCLUDEPATH". (This has now been fixed on the web site.)

2. jtux_file.c, around line 160: change return type for Java_jtux_UFile_dup2 from "int" to "jint".

3. jtux_network.c, around line 334: remove the open brace at the end of the line, as it's not closed.

4. jtux_network.c, around line 710: sockatmark isn't defined in Darwin, so add that condition to the existing #if:
	#if _XOPEN_VERSION >= 600 && !defined(DARWIN)

5. jtux_posixipc.c: bracket entire file after the #include of defs.h with this #if:

#if (_POSIX_MESSAGE_PASSING > 0) && (_POSIX_SEMAPHORES > 0) && (_POSIX_SHARED_MEMORY_OBJECTS > 0)

and a matching #endif at the end.

6. jtux_process.c, around line 520: replace the return statement with this:
	#if _POSIX_REALTIME_SIGNALS > 0
		return SIGRTMIN;
	#else
		return 0;
	#endif

and do the same in the function Java_jtux_UProcess_sig_1get_1SIGRTMAX:
	#if _POSIX_REALTIME_SIGNALS > 0
		return SIGRTMAX;
	#else
		return 0;
	#endif

7. jtux_sysvipc.c, around line 181:  change return type for Java_jtux_USysVIPC_semctl from "int" to "jint".

around line 24: surround the POSIX IPC include like this:
	#if _POSIX_MESSAGE_PASSING > 0
	#include <mqueue.h>
	#endif
and similarly around lines 182 and 198:
	#if _POSIX_MESSAGE_PASSING > 0
		if (sizeof(jint) < sizeof(nfds_t)) {
			ok = false;
			fprintf(stderr, "Type size error: sizeof(jint) < sizeof(nfds_t)\n");
		}
	#endif

	#if _POSIX_MESSAGE_PASSING > 0
		if (sizeof(jlong) < sizeof(mqd_t)) {
			ok = false;
			fprintf(stderr, "Type size error: sizeof(jlong) < sizeof(mqd_t)\n");
		}
	#endif

8. jtux_sysvipc.c, around line 245: the #include ought not use a relative path; change it to:
	#include "macrostr.incl"

9. macrostr.incl, around line 186: SIGPOLL seems not to be defined in Darwin, so change the #ifdef to:
	#if defined(_XOPEN_UNIX) && !defined(DARWIN)

10. jtux_file.c, around line 241: fdatasync isn't defined in Darwin, so change the body of the function Java_jtux_UFile_fdatasync to:
	#ifndef DARWIN
		JTHROW_neg1(fdatasync(fd))
	#else
		(void)setup_throw_errno(env, ENOSYS);
		return -1;
	#endif
