.Dd December 21, 2001 .Dt MAC_TEXT 3 .Os .Sh NAME .Nm mac_from_text , .Nm mac_to_text .Nd convert MAC label to/from text representation .Sh LIBRARY .Lb libc .Sh SYNOPSIS n sys/mac.h .Ft int .Fn mac_from_text "mac_t *mac" "const char *text" .Ft int .Fn mac_to_text "mac_t label" "char **text" .Sh DESCRIPTION The .Fn mac_from_text function converts the text representation of a label into the internal policy label format
q Vt mac_t and places it in .Fa *mac , which must later be freed with .Xr free 3 .
p The .Fn mac_to_text function allocates storage for .Fa *text , which will be set to the text representation of .Fa label .
p Refer to .Xr maclabel 7 for the MAC label format. .Sh RETURN VALUES .Rv -std mac_from_text mac_to_text .Sh COMPATIBILITY POSIX.1e does not define a format for text representations of MAC labels.
p POSIX.1e requires that text strings allocated using .Fn mac_to_text be freed using .Xr mac_free 3 ; in the .Fx implementation, they must be freed using .Xr free 3 , as .Xr mac_free 3 is used only to free memory used for type .Vt mac_t . .Sh ERRORS l -tag -width Er t Bq Er ENOMEM Insufficient memory was available to allocate internal storage. .El .Sh SEE ALSO .Xr free 3 , .Xr mac 3 , .Xr mac_get 3 , .Xr mac_is_present 3 , .Xr mac_prepare 3 , .Xr mac_set 3 , .Xr posix1e 3 , .Xr mac 4 , .Xr maclabel 7 .Sh STANDARDS POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion of the draft continues on the cross-platform POSIX.1e implementation mailing list. To join this list, see the .Fx POSIX.1e implementation page for more information. .Sh HISTORY Support for Mandatory Access Control was introduced in .Fx 5.0 as part of the .Tn TrustedBSD Project.
