getseuserbyname - Man Page

#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.
