Detecting Keyboard Input without return
Hi,
I need a way to detect the up and down arrow key inputs for my program. I do not want to wait for the return key to be entered(so that rules out getch() and family). Also I need to process several of these inputs in parallel, by servicing each request with a thread.
Is that possible?

selabel_lookup
selabel_lookup(3) SELinux API documentation selabel_lookup(3)
NAME
selabel_lookup - obtain SELinux security context from a string label.
SYNOPSIS
#include <selinux/selinux.h>
#include <selinux/label.h>
int selabel_lookup(struct selabel_handle *hnd,
security_context_t *context,
const char *key, int type);
int selabel_lookup_raw(struct selabel_handle *hnd,
security_context_t *context,
const char *key, int type);
DESCRIPTION
selabel_lookup performs a lookup operation on the handle hnd, returning the result in the memory pointed to by context, which must be freed
by the caller using freecon(3). The key and type parameters are the inputs to the lookup operation and are interpreted according to the
specific backend that handle is open on.
selabel_lookup_raw behaves identically to selabel_lookup but does not perform context translation.
RETURN VALUE
On success, zero is returned. On error, -1 is returned and errno is set appropriately.
ERRORS
ENOENT No context corresponding to the input key and type was found.
EINVAL The key and/or type inputs are invalid, or the context being returned failed validation.
ENOMEM An attempt to allocate memory failed.
