NAME
safe_ow_scale_vector_by_sum - Scales a vector so that the sum of elements is 1
SYNOPSIS
#include "m/m_vec_norm.h"
Example compile flags (system dependent):

int safe_ow_scale_vector_by_sum(Vector *vp);
DESCRIPTION
This routine is like ow_scale_vector_by_sum(3), except that if the scale were
to lead to divide by zero, then a warning message is printed, and the vector
is set to uniform values.
If "vp" is NULL, then this routine simply returns NO_ERROR.
RETURNS
NO_ERROR on success, ERROR on failure.
DISCLAIMER
This software is not adequatedly tested. It is recomended that
results are checked independantly where appropriate.
