Dear R experts,
In all R functions written in C one must unprotect
result before returning them:
{
...
UNPROTECT(1) /* unprotecting `ans' */
return ans;
}
Why does one shure that memory occupied by `ans'
won't be used by R immediately after unprotecting?
Ok, is the next construction also absolutely safe?
{
...
UNPROTECT(1) /* unprotecting `ans' */
PROTECT( val = ans )
...
}
Thanks a lot!
