NAME         top

       getseuserbyname - get SELinux username and level for a given Linux
       username

SYNOPSIS         top

       #include <selinux/selinux.h>

       int getseuserbyname(const char *linuxuser, char **selinuxuser,
       char **level);

DESCRIPTION         top

       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.

RETURN VALUE         top

       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.
