.SH DESCRIPTION
.ad l
These functions provide a way for libarchive clients to configure
specific read modules.
.RS 5
.TP
\fB\%archive_read_set_filter_option\fP(),
\fB\%archive_read_set_format_option\fP()
Specifies an option that will be passed to currently-registered
filters (including decompression filters) or format readers.
.PP
If
\fIoption\fP
and
\fIvalue\fP
are both
.BR NULL,
these functions will do nothing and
\fBARCHIVE_OK\fP
will be returned.
If
\fIoption\fP
is
.BR NULL
but
\fIvalue\fP
is not, these functions will do nothing and
\fBARCHIVE_FAILED\fP
will be returned.
.PP
If
\fImodule\fP
is not
.BR NULL,
\fIoption\fP
and
\fIvalue\fP
will be provided to the filter or reader named
\fImodule\fP.
The return value will be that of the module.
If there is no such module,
\fBARCHIVE_FAILED\fP
will be returned.
.PP
If
\fImodule\fP
is
.BR NULL,
\fIoption\fP
and
\fIvalue\fP
will be provided to every registered module.
If any module returns
\fBARCHIVE_FATAL\fP,
this value will be returned immediately.
Otherwise,
\fBARCHIVE_OK\fP
will be returned if any module accepts the option, and
\fBARCHIVE_FAILED\fP
in all other cases.
.TP
\fB\%archive_read_set_option\fP()
Calls
\fB\%archive_read_set_format_option\fP(),
then
\fB\%archive_read_set_filter_option\fP().
If either function returns
\fBARCHIVE_FATAL\fP,
\fBARCHIVE_FATAL\fP
will be returned
immediately.
Otherwise, greater of the two values will be returned.
.TP
\fB\%archive_read_set_options\fP()
\fIoptions\fP
is a comma-separated list of options.
If
\fIoptions\fP
is
.BR NULL
or empty,
\fBARCHIVE_OK\fP
will be returned immediately.
.PP
Calls
\fB\%archive_read_set_option\fP()
with each option in turn.
If any
\fB\%archive_read_set_option\fP()
call returns
\fBARCHIVE_FATAL\fP,
\fBARCHIVE_FATAL\fP
will be returned immediately.
.PP
Individual options have one of the following forms:
.RS 5
.TP
\fIoption=value\fP
The option/value pair will be provided to every module.
Modules that do not accept an option with this name will ignore it.
.TP
\fIoption\fP
The option will be provided to every module with a value of
``1''.
.TP
\fI!option\fP
The option will be provided to every module with a NULL value.
.TP
\fImodule:option=value\fP, \fImodule:option\fP, \fImodule:!option\fP
As above, but the corresponding option and value will be provided
only to modules whose name matches
\fImodule\fP.
