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

     kvm_geterr -- get error message on kvm descriptor

     Kernel Data Access Library (libkvm, -lkvm)

     #include <kvm.h>

     char *
     kvm_geterr(kvm_t *kd);

     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.

     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)

     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().
