TIOCEXCL(2const) TIOCEXCL(2const)
TIOCEXCL, TIOCGEXCL, TIOCNXCL - exclusive mode
Standard C library (libc, -lc)
#include <asm/termbits.h> /* Definition of TIOC*XCL constants */ #include <sys/ioctl.h> int ioctl(int fd, TIOCEXCL); int ioctl(int fd, TIOCGEXCL, int *argp); int ioctl(int fd, TIOCNXCL);
TIOCEXCL Put the terminal into exclusive mode. No further open(2) operations on the terminal are permitted. (They fail with EBUSY, except for a process with the CAP_SYS_ADMIN capability.) TIOCGEXCL If the terminal is currently in exclusive mode, place a nonzero value in the location pointed to by argp; otherwise, place zero in *argp. TIOCNXCL Disable exclusive mode.
On success, 0 is returned. On error, -1 is returned, and errno is set to indicate the error.
TIOCGEXCL Linux 3.8.
