getseuserbyname - get SELinux username and level for a given Linux username
#include <selinux/selinux.h>
int getseuserbyname(const char *linuxuser, char
**selinuxuser, char **level);
getseuserbyname() retrieves the SELinux username and security level
associated with a given Linux username. The SELinux username and security
level can then be passed to other libselinux functions such as
get_ordered_context_list_with_level(3) and
get_default_context_with_level(3).
The returned SELinux username and level should be freed by the caller using
free.
On success, 0 is returned. On failure, -1 is returned and
errno is set
appropriately.
The errors documented for the
stat(2) system call are also applicable
here.
