   selabel_lookup    ( 3 )

получить контекст безопасности SELinux из строковой метки (obtain SELinux security context from a string label)

Имя (Name)

selabel_lookup - obtain SELinux security context from a string
       label

Синопсис (Synopsis)

#include <selinux/selinux.h>
       #include <selinux/label.h>

int selabel_lookup(struct selabel_handle *hnd, char **context, const char *key, int type);

int selabel_lookup_raw(struct selabel_handle *hnd, char **context, const char *key, int type);


Описание (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.


Возвращаемое значение (Return value)

On success, zero is returned.  On error, -1 is returned and errno
       is set appropriately.

Ошибки (Error)

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.
