I think this is a clean patch. It should work on any glibc2.1 system AFAIK. I can only test it on glibc2.1 w/pty98 support. It seems OK: The conditional code is moved to process.h. I suppose that's where it should go(?) 1. M-x shell 2. tty > /dev/pts/1 (good) 3. C-x k 4. M-x shell 5. tty > /dev/pts/1 (good) 6. M-x rename buffer *shell2* 7. M-x shell 8. tty > /dev/pts/2 (good) Index: process.h =================================================================== RCS file: /usr/CVSroot/XEmacs/xemacs/src/process.h,v retrieving revision 1.8 diff -u -r1.8 process.h --- process.h 1998/04/11 05:37:05 1.8 +++ process.h 1999/07/29 02:19:51 ＠＠ -134,4 +134,16 ＠＠ #endif /* emacs */ +#if defined (__GLIBC__) && (__GLIBC__ >= 2) && (__GLIBC_MINOR__ >= 1) +# define HAVE_GETPT +#endif + +#ifdef HAVE_GETPT +#define PTY_ITERATION +#define PTY_OPEN \ + if ((fd = getpt()) < 0 || grantpt (fd) < 0 || unlockpt (fd) < 0) \ + return -1; +#define PTY_TTY_NAME_SPRINTF ptsname_r (fd, pty_name, sizeof (pty_name)); +#endif + #endif /* _XEMACS_PROCESS_H_ */ Index: process-unix.c =================================================================== RCS file: /usr/CVSroot/XEmacs/xemacs/src/process-unix.c,v retrieving revision 1.11.2.5 diff -u -r1.11.2.5 process-unix.c --- process-unix.c 1998/12/29 10:54:27 1.11.2.5 +++ process-unix.c 1999/07/29 02:20:04 ＠＠ -216,6 +216,7 ＠＠ int fd; int c; + #ifdef PTY_ITERATION PTY_ITERATION #else ＠＠ -265,7 +266,7 ＠＠ if (access (pty_name, 6) != 0) { close (fd); -#if !defined(IRIS) && !defined(__sgi) +#if !defined(IRIS) && !defined(__sgi) && !defined (HAVE_GETPT) continue; #else return -1;
