#include <keyutils.h> key_serial_t find_key_by_type_and_name(const char *type, const char *description, key_serial_t destringid);
find_key_by_type_and_name() searches for a key with the given type and exact description, firstly in the thread, process and session keyrings to which a process is subscribed and secondly in /proc/keys.
If a key is found, and destringid is not 0 and specifies a keyring, then the found key will be linked into it.
The function returns the ID of the key if a key was found or -1 otherwise.
When linking, -lkeyutils should be specified to the linker.
