vhangup - virtually hangup the current terminal
Standard C library (libc, -lc)
#include <unistd.h>
int vhangup(void);
vhangup():
Since glibc 2.21:
_DEFAULT_SOURCE
In glibc 2.19 and 2.20:
_DEFAULT_SOURCE || (_XOPEN_SOURCE && _XOPEN_SOURCE < 500)
Up to and including glibc 2.19:
_BSD_SOURCE || (_XOPEN_SOURCE && _XOPEN_SOURCE < 500)
vhangup() simulates a hangup on the current terminal. This call arranges for other users to have a “clean” terminal at login time.
On success, zero is returned. On error, -1 is returned, and errno is set to indicate the error.
This call is Linux-specific, and should not be used in programs intended to be portable.
