kvm_geterr - get error message on kvm descriptor
This function returns a string describing the most recent
on the descriptor kd. The results are undefined if the most
kvm(3) library call did not produce an error. The string
stored in memory owned by kvm(3) so the message should be
copied out and
saved elsewhere if necessary.
kvm(3), kvm_close(3), kvm_getargv(3), kvm_getenvv(3),
kvm_nlist(3), kvm_open(3), kvm_openfiles(3), kvm_read(3),
This routine cannot be used to access error conditions due
to a failed
kvm_openfiles() call, since failure is indicated by returning a NULL descriptor.
Therefore, errors on open are output to the special error
buffer passed to kvm_openfiles(). This option is not available to
