DCMD_PROC_SIGNAL

Drop a signal on the process that's associated with the file descriptor. This is a way for a debugger to artificially generate signals as if they came from the system.

The argument is a pointer to a procfs_signal structure that specifies the signal to send. For example:

procfs_signal   signal;

signal.tid = 0;
signal.signo = SIGCONT;
signal.code = 0;
signal.value = 0;

devctl( fd, DCMD_PROC_SIGNAL, &signal, sizeof signal, NULL);
