Need Some help writing a module.

Hi all, I'm writing a PHP module for repat, a C-based RDF parser, very similar to expat, in fact it uses expat but for RDF statements. Maybe some of you with a lot of experience in writing modules can help me with my problem I have a C variable, a pointer with say X and when I pass the pointer to a function it receives not X but something else. This is a dump of a silly gdb session showing the problem (using the binary php) See how report_start_element receies an rdf_parser and that rdf_parser->user_data is 0x81970c Then this code is executed: if( rdf_parser->start_element_handler ) { ( *rdf_parser->start_element_handler )( rdf_parser->user_data, name, attributes ); } and parser_my_start_element (the function acting as start_element_handler) receives 0x1cd (???!!) This is the dump Breakpoint 1, report_start_element (rdf_parser=0x81f9a58, name=0x81fa714 "html", attributes=0x81f9ce0) at rdfparse.c:1292 1292 if( rdf_parser->start_element_handler ) (gdb) s 1294 ( *rdf_parser->start_element_handler )( (gdb) p rdf_parser->user_data $12 = (void *) 0x81f970c (gdb) s Breakpoint 2, parser_my_start_element_handler (user_data=0x1cd, name=0x81fa714 "html", attributes=0x81f9ce0) at repat.c:653 If someone can give me a tip about what may be happening then I'd get back to continue the module, after this problem it should be ready next week since everything was on wheels until now.
