[OpenSIPS-Users] $var(NAME) = NULL; what is the value ?

I guess that documentation needs to be updated because it appears NULL support was added to pseudo vars at some point. I traced down the pvar assignment in gdb where the flag was NULL and it was assigned str_null:

static char _str_null_hlp[7] = {'<','n','u','l','l','>',0};
static str str_null   = { _str_null_hlp, 6 };

The default used to by PV_VAL_INT I guess which always initialized to 0… however this may have posed a problem along the way when actually needing to represent a NULL value returned from a database or something else.
