Overview
This function returns a string describing the most recent error condition on the descriptor kd. The results are undefined if the most recent kvm(3) library call did not produce an error. The string returned is stored in memory owned by kvm(3) so the message should be copied out and saved elsewhere if necessary.
Return values
The function kvm_geterr() will return "" if kd is NULL or an error has not been captured for kd.
