selabel_lookup(3) SELinux API documentation selabel_lookup(3)NAMEselabel_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, 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.
