TSRMLS_C and TSRMLS_CC - afaik, yes MYEXTENSION_G(the_tree) - whatever define you use (e.g., FOOG(bar)) p.s.: _C is used when a function takes no arguments, _CC is used otherwise void func1() - define as "void func1(TSRMLS_D)", call as "func1(TSRMLS_C)" void func2(params) - define as "void func2(params TSRMLS_DC)", call as "func2(params TSRMLS_CC)" S> And finally, should I malloc all the nodes with malloc or emalloc ? emalloc() S> The second thing is related : S> If I put in PHP_MINIT_FUNCTION: S> and in PHP_MSHUTDOWN_FUNCTION: sorry, i don't know why it happens -- Best regards, val mailto:val@vk.kiev.ua
