I use SCO UNIX 5.07 on a Compaq Proliant Machine. Each time I press the Escape or Delete key while running a program or issuing a FoxBase+ command from the dot prompt, I receive the error message: "Memory Fault - Core Dumped" and the screen locks up immediately.

Can anyone tell me why I keep getting a Segmentation fault when I try to run tilda?
$ tilda
Segmentation fault (core dumped)
It seemed to run after I deleted my tilda directory like this thread said to do. Unfortunately it wouldn't let me set my keybinding with anything I tried.

clock_getcpuclockid
CLOCK_GETCPUCLOCKID(3) Linux Programmer's Manual CLOCK_GETCPUCLOCKID(3)NAME
clock_getcpuclockid - obtain ID of a process CPU-time clock
SYNOPSIS
#include <time.h>
int clock_getcpuclockid(pid_t pid, clockid_t *clock_id);
Link with -lrt (only for glibc versions before 2.17).
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
clock_getcpuclockid():
_XOPEN_SOURCE >= 600 || _POSIX_C_SOURCE >= 200112L
DESCRIPTION
The clock_getcpuclockid() function obtains the ID of the CPU-time clock of the process whose ID is pid, and returns it in the location
pointed to by clock_id. If pid is zero, then the clock ID of the CPU-time clock of the calling process is returned.
RETURN VALUE
On success, clock_getcpuclockid() returns 0; on error, it returns one of the positive error numbers listed in ERRORS.
ERRORS
ENOSYS The kernel does not support obtaining the per-process CPU-time clock of another process, and pid does not specify the calling
process.
EPERM The caller does not have permission to access the CPU-time clock of the process specified by pid. (Specified as an optional error
in POSIX.1-2001; does not occur on Linux unless the kernel does not support obtaining the per-process CPU-time clock of another
process.)
ESRCH There is no process with the ID pid.
VERSIONS
The clock_getcpuclockid() function is available in glibc since version 2.2.
ATTRIBUTES
Multithreading (see pthreads(7))
The clock_getcpuclockid() function is thread-safe.
CONFORMING TO
POSIX.1-2001.
NOTES
Calling clock_gettime(2) with the clock ID obtained by a call to clock_getcpuclockid() with a pid of 0, is the same as using the clock ID
CLOCK_PROCESS_CPUTIME_ID.
EXAMPLE
The example program below obtains the CPU-time clock ID of the process whose ID is given on the command line, and then uses clock_get-
time(2) to obtain the time on that clock. An example run is the following:
$ ./a.out 1 # Show CPU clock of init process
CPU-time clock for PID 1 is 2.213466748 seconds
Program source
#define _XOPEN_SOURCE 600
#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
#include <time.h>
int
main(int argc, char *argv[])
{
clockid_t clockid;
struct timespec ts;
if (argc != 2) {
fprintf(stderr, "%s <process-ID>
", argv[0]);
exit(EXIT_FAILURE);
}
if (clock_getcpuclockid(atoi(argv[1]), &clockid) != 0) {
perror("clock_getcpuclockid");
exit(EXIT_FAILURE);
}
if (clock_gettime(clockid, &ts) == -1) {
perror("clock_gettime");
exit(EXIT_FAILURE);
}
printf("CPU-time clock for PID %s is %ld.%09ld seconds
",
argv[1], (long) ts.tv_sec, (long) ts.tv_nsec);
exit(EXIT_SUCCESS);
}
