Added dbFreeLinkInfo(), use everywhere to release dbLinkInfo resources.
Renamed link_type => expected_type in db[Can]SetLink(),
my brain understands this name faster.
This required a change to the lset::getValue arguments, removing
the pstat and psevr pointers. Links can still return a non-zero
value from getValue and trigger a LINK:INVALID alarm, but for any
other alarm settings they must manipulate the record themselves.
The JSON parser passes string arguments with a length
instead or nil-terminating them. These routines make it
simple to copy such strings into either permanent or
temporary storage.
* Added new lset::openLink() method, called on JSON_LINKs only
* Cleanup in dbJLink.c to prevent memory leaks.
* Removed jlif::start_parse() method.
* Renamed jlif::end_parse() to end_child, which will be called on
the parent link when a child link has succesfully finished parsing.
The long string in/out records use a different initializer
for constant links. The new loadLS method allows a constant
link type to initialize such a long string field.
NB: This routine was added in the middle of the lset table.
Any external link support implementations must be adjusted.
The lnkConst.c implementation is not yet complete, no support for arrays of
strings (JMOP).
Link error messages should display their record & field name, which is not yet
possible.
The ability to embed links as parameters to other link types is not complete
yet; this will be required for the calc link type.
This code currently passes all existing tests, but additional tests are needed
for the new functionality.
Replace lset::loadLink with lset::loadScalar, add lset::loadArray
Add dbLoadLinkArray() routine to dbLink.h API
New dbConvertJSON.h API for use by dbConstLoadArray()
Both Perl and dbStaticLib support included.
Also added a new std/link directory for link types.
Nothing looks up the registered link support tables yet.
