Description: This dirty hack fixes segfaults if Tcl is built with stubs
|
|
and Expect is used directly from C program.
|
|
Bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=588817
|
|
Example:
|
|
#include <stdio.h>
|
|
#include <tcl8.5/expect.h>
|
|
int main()
|
|
{
|
|
FILE *pipe;
|
|
char *some_command = "uname";
|
|
char datum;
|
|
pipe = exp_popen(some_command);
|
|
if (pipe == NULL) return 1;
|
|
while ((datum = getc (pipe)) != EOF)
|
|
printf("%c",datum);
|
|
}
|
|
Example:
|
|
#include <stdio.h>
|
|
#include "expect.h"
|
|
main()
|
|
{
|
|
int fd = 0;
|
|
fd = exp_spawnl("echo", "echo", "Hello User: Whats up?", (char*) 0);
|
|
switch (exp_expectl(fd, exp_regexp, "ser:", 1, exp_end)) {
|
|
case 1: {
|
|
printf("GOT ser:\n");
|
|
break;
|
|
}
|
|
default: {
|
|
printf("DEFAULT\n");
|
|
return 1;
|
|
}
|
|
}
|
|
printf("Normal Exit\n");
|
|
return 0;
|
|
}
