KVM_GETERR(3) UNIX Programmer’s Manual KVM_GETERR(3)
NAME
kvm_geterr - get error message on kvm descriptor
SYNOPSIS
#include <kvm.h>
char *
kvm_geterr(kvm_t *kd)
DESCRIPTION
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.
BUGS
This routine cannot be used to access error conditions due
to a failed
kvm_openfiles() call, since failure is indicated by
returning a NULL de-
scriptor. Therefore, errors on open are output to the
special error
buffer passed to kvm_openfiles(). This option is not
available to
kvm_open().
