How long are the TSRMLS_D/C parameters good for?
Can the resultant tsrm_ls value be safely stored?
I presume the answer is no, and these paramters
should be passed in each time a function is called,
but I would be curious to know differently, if for example
it could be passed in once at (external object) creation time,
and that object could use the trsm_ls directly, rather than the
TSRMLS_D/C semantics.
...
Otherwise it seems clear that an external object outside php
cannot use php semantics, so cannot use the php_stream wrappers.
...
That being the case, an external object (referenced from within eg:
a php extension) must either:
a. be able to ignore php-streams and use system streams directly
(not obviously apparent, given errors experienced to date)
or
b. cannot use system streams when calls originate from php/extensions,
(in which case no 3rd party objects which access streams are reliable in
php/extensions)
Clearly a. is more desirable than b. , despite the fact that an apparently
reliable 3rd party object did generate errors when called from within a
php-extension.
---
This is my third attempt to ask for a clear answer as to whether a. or b.
is correct, so hopefully someone will notice, has the answer, and can respond.
Cheers,
Andrew.
