kvm_geterr(3) [netbsd man page]

KVM_GETERR(3)						   BSD Library Functions Manual 					     KVM_GETERR(3)

NAME

     kvm_geterr -- get error message on kvm descriptor

LIBRARY

     Kernel Data Access Library (libkvm, -lkvm)

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.

SEE ALSO

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

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
     descriptor.  Therefore, errors on open are output to the special error buffer passed to kvm_openfiles().  This option is not available to
     kvm_open().
