mac_from_msen(3C)

NAME
     mac_from_msen, mac_from_mint, mac_from_msen_mint - convert independent
     sensitivity or integrity labels to mac_t

SYNOPSIS
     #include <sys/mac.h>

     mac_t mac_from_msen(msen_t msen);
     mac_t mac_from_mint(mint_t mintp);
     mac_t mac_from_msen_mint(msen_t msenp, mint_t mintp);

DESCRIPTION
     mac_from_msen       Return a mac_t constructed from the given msen label,
                         substituting MINT_EQUAL_LABEL for the needed mint
                         component.

     mac_from_mint       Return a mac_t constructed from the given mint label,
                         substituting MSEN_EQUAL_LABEL for the needed msen
                         component.

     mac_from_msen_mint  Return a mac_t constructed from the given msen and
                         mint labels.

RETURN VALUES
     mac_from_msen returns a mac_t, a pointer to an allocated struct
     mac_label, or a NULL pointer in the case of a failure.  The mac_t should
     be freed when no longer needed by calling mac_free(3c).

     mac_from_mint returns a mac_t, a pointer to an allocated struct
     mac_label, or a NULL pointer in the case of a failure.  The mac_t should
     be freed when no longer needed by calling mac_free(3c).

     mac_from_msen_mint returns a mac_t, a pointer to an allocated struct
     mac_label, or a NULL pointer in the case of a failure.  The mac_t should
     be freed when no longer needed by calling mac_free(3c).
