error stack

I would like to add better error handling to the imap_* functions. My current plan is something like this: New function: php3_imap_init_error_queue() - this would return an empty array (ie, $foo = imap_init_error_queue(); (i'll take a shorter name suggestion if you've got one) Change to mm_log: - if imap_init_error_queue() has been called, add errors to the error queue instead of php3_error()ing them. - otherwise, splat them to the browser (depending on error level) - the current behavior. If that makes sense, here are my questions: Are there any functions that are called on page start and end? It seems like I'll need a global variable of some sort, or a symbol table entry. How do I clean it up/make sure it's initialized properly? Using a symbol table entry, how would I get the name of the var on the other side of the = ? The example code in apidoc.txt is: hash_update(active_symbol_table,"foo",sizeof("foo"),&arr,sizeof(pval),NULL); What do I replace "foo" with so that $foo = imap_init_error_queue() and $bar = imap_init_error_queue() both work? Or is there a different function I'm missing? The other thing I thought of was sticking: pval *imap_error_queue = NIL; in imap.c. Then mm_log would check that for NIL; if it was NIL it would php3_error(); if it was set to something then it would add an array entry to it. The problem seems to be making sure that it's always set to NIL on a page load. Also, where would I free() (efree?) the error queue? If it sounds like I con't know what I'm doing in c, I probably don't. Hopefully someone can help me out without me being too much of a nuisance.
