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().
