|
|
|

|
.Sh SYNOPSIS
|
|
|
|
|
.Fd #include <kvm.h>
|
|
|
|
|

|
|
|
|
|
.Ft char *

.Fn kvm_geterr "kvm_t *kd"
|
|
|
|
|
.Sh DESCRIPTION
|
|
|
|
|
This function returns a string describing the most recent error condition
|
|
|
|
|
on the descriptor
|
|
|
|
|
.Fa kd .
|
|
|
|
|
The results are undefined if the most recent
|
|
|
|
|
.Xr kvm 3
|
|
|
|
|
library call did not produce an error.
|
|
|
|
|
The string returned is stored in memory owned by
|
|
|
|
|
.Xr kvm 3
|
|
|
|
|
so the message should be copied out and saved elsewhere if necessary.
|
|
|
|
|
.Sh BUGS
|
|
|
|
|
This routine cannot be used to access error conditions due to a failed
|
|
|
|
|
.Fn kvm_openfiles
|
|
|
|
|
call, since failure is indicated by returning a
|
|
|
|
|
.Dv NULL
|
|
|
|
|
descriptor.
|
|
|
|
|
Therefore, errors on open are output to the special error buffer
|
|
|
|
|
passed to
|
|
|
|
|
.Fn kvm_openfiles .
|
|
|
|
|
This option is not available to
|
|
|
|
|
.Fn kvm_open .
