From: mike Date: Mon, 17 Oct 2005 13:42:43 +0000 (+0000) Subject: Revert "const char*" arguments to their original const-qualified X-Git-Tag: cpan_1_22~450 X-Git-Url: http://jsfdemo.indexdata.com/cgi-bin?a=commitdiff_plain;h=3e0c6a2e1651cbc655d1acfd7ecf317745c29803;p=ZOOM-Perl-moved-to-github.git Revert "const char*" arguments to their original const-qualified types, now that I have modified the typemap to support this. Add "opaquechar" and "struct datachunk" types, used to get binary data strings in and out of C respectively. These are used by ZOOM_connection_option_setl() and ZOOM_connection_option_getl() respectively. Implemented ZOOM_connection_error_x(). Tested ZOOM_connection_{errcode,errmsg,addinfo)(). Tested ZOOM_options_create(). Add explicit "UNTESTED" markers to not-yet-tested functions. --- diff --git a/ZOOM.xs b/ZOOM.xs index 8da6efc..78b0508 100644 --- a/ZOOM.xs +++ b/ZOOM.xs @@ -1,4 +1,4 @@ -/* $Id: ZOOM.xs,v 1.12 2005-10-13 13:48:08 mike Exp $ */ +/* $Id: ZOOM.xs,v 1.13 2005-10-17 13:42:43 mike Exp $ */ #include "EXTERN.h" #include "perl.h" @@ -6,23 +6,24 @@ #include +/* Used by the *_setl() functions */ +typedef char opaquechar; + +/* Used as the return value of the *_getl() functions */ +struct datachunk { + char *data; + int len; +}; MODULE = Net::Z3950::ZOOM PACKAGE = Net::Z3950::ZOOM PREFIX=ZOOM_ PROTOTYPES: ENABLE -# It seems that when one of these functions is called from Perl with -# a string-constant argument, that is not recognised as suitable to -# be mapped onto a "const char*" argument.
