.SH "NAME"
set_matchpathcon_flags, set_matchpathcon_invalidcon, set_matchpathcon_printf \- set flags controlling the operation of matchpathcon or matchpathcon_index and configure the behaviour of validity checking and error displaying.

.B #include <selinux/selinux.h>

.BI "void set_matchpathcon_flags(unsigned int " flags ");"

.BI "void set_matchpathcon_invalidcon(int (*" f ")(const char *" path ", unsigned " lineno ", char * " context "));"

.BI "void set_matchpathcon_printf(void (*" f ")(const char *" fmt ", ...));"

.SH "DESCRIPTION"
.B set_matchpathcon_flags
sets the flags controlling the operation of 
.B matchpathcon_init
and subsequently
.B matchpathcon_index
or
.B matchpathcon.
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

.B set_matchpathcon_invalidcon
sets the function used by 
.B matchpathcon_init
when checking the validity of a context in the file contexts
configuration.  If not set, then this defaults to a test based 
on 
.B 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 
.B 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

.B set_matchpathcon_printf
sets the function used by 
.B matchpathcon_init
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.
.sp

.SH "RETURN VALUE"
Returns zero on success or \-1 otherwise.
