NAME    [Toc]    [Back]

     kvm_geterr - get error message on kvm descriptor

SYNOPSIS    [Toc]    [Back]

     #include <kvm.h>

     char *
     kvm_geterr(kvm_t *kd);

DESCRIPTION    [Toc]    [Back]

     This function returns a string describing  the  most  recent
error condition
     on the descriptor kd.  The results are undefined if the most
     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.

SEE ALSO    [Toc]    [Back]

     kvm(3),   kvm_close(3),   kvm_getargv(3),    kvm_getenvv(3),
     kvm_nlist(3),  kvm_open(3),  kvm_openfiles(3),  kvm_read(3),

BUGS    [Toc]    [Back]

     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
