Further R-devel changes making things a little easier on attribute access #1432
Description
This morning via the RSS feed of NEWS changes:
- New function ‘R_getAttributes’ returns the same result as the R function ‘attributes’. New functions ‘R_getAttribCount’, ‘R_getAttribNames’, ‘R_hasAttrib’, ‘R_nrow’, and ‘R_ncol’.
What we added of course still works, but these additions should make things generally simpler. There is a bit more in the entry mostly on ALTREP.
PS Interestingly R_nrow and R_ncol return int so if we used them we'd break interface again as we standardised on R_xlen_t. Or we would have to (needlessly ?) cast up.
PPS I also emailed with Luke who responded that he was also going back and forth on that but that given how dim attributes are still 32 bit a lot more would have to change. Possibly at a later point...
PPPS Hah! And just I typed the previous comment I also refresh SVN and voilà we have

Change return types for R_nrow and R_ncl to R_xlen_t.
Thanks @ltierney !
