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);
DESCRIPTIONselabel_lookup() performs a lookup operation on the handle hnd, returnā
ing 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.
