The serial number will be returned if that key exists. If the key or keyring does not yet exist, then if…
keyctl_describe – Describe a key Synopsis#include <keyutils.h> long keyctl_describe(key_serial_t key, char *buffer, size_tbuflen); long keyctl_describe_alloc(key_serial_t key, char **_buffer);Descriptionkeyctl_describe() describes the attributes of a key as a NUL-terminated string. The caller must have view permission on a key to be able to get a description of it. buffer and buflen specify the buffer into which the…
keyctl_clear – Clear a keyring Synopsis#include <keyutils.h> long keyctl_clear(key_serial_t keyring);Descriptionkeyctl_clear() clears the contents of a keyring. The caller must have write permission on a keyring to be able clear it. Return ValueOn success keyctl_clear() returns 0. On error, the value -1 will be returned and errno will have been set to an appropriate error. ErrorsENOKEY…
keyctl_chown – Change the ownership of a key Synopsis#include <keyutils.h> long keyctl_chown(key_serial_t key, uid_t uid, gid_t gid);Descriptionkeyctl_chown() changes the user and group ownership details of a key. A setting of -1 on either uid or gid will cause that setting to be ignored. A process that does not have the SysAdmin capability may not change…
keyctl_*() – Key management function wrappers DescriptionThe keyctl() system call is a multiplexor for a number of key management functions. These should be called via the wrappers in the libkeyutils library. The functions can be compiled in by including the keyutils header file: #include <keyutils.h> and then telling the linker it should link in the…
keyboard_ucallback – User specified unicode keyboard callback handler. Allegro game programming library. Synopsis#include <allegro.h> extern int (*keyboard_ucallback)(int key, int *scancode); DescriptionUnicode-aware version of keyboard_callback().
