.SH "DESCRIPTION"
.BR set_matchpathcon_flags ()
sets the flags controlling the operation of 
.BR matchpathcon_init (3)
and subsequently
.BR matchpathcon_index (3)
or
.BR matchpathcon (3).
If the 
.B MATCHPATHCON_BASEONLY
flag is set, then only the base file contexts configuration file
will be processed, not any dynamically generated entries or local customizations.
.sp

.BR set_matchpathcon_invalidcon ()
sets the function used by 
.BR matchpathcon_init (3)
when checking the validity of a context in the file contexts
configuration.  If not set, then this defaults to a test based 
on 
.BR security_check_context (3),
which checks validity against the active policy on a SELinux system.
This can be set to instead perform checking based on a binary policy file,
e.g. using 
.BR sepol_check_context (3),
as is done by 
.B setfiles \-c.
The function is also responsible for reporting any such error, and
may include the 
.I path
and
.I lineno
in such error messages.
.sp

.BR set_matchpathcon_printf ()
sets the function used by 
.BR matchpathcon_init (3)
when displaying errors about the file contexts configuration.  If not set, 
then this defaults to fprintf(stderr, fmt, ...).  This can be set to redirect
error reporting to a different destination.
.
.SH "RETURN VALUE"
Returns zero on success or \-1 otherwise.
