**
** DESCRIPTION
-** The subst_var_value() changes the value of msh->envp
+** The u_subst_var_value() function changes the value of msh->envp
** variable varname[] with newval[]. If varname[] wasn't found
** in msh->envp, varname[] is searched in msh->vars. Otherwise
** varname[] is added to msh->vars.
+**
+** RETURN VALUES
+** The u_subst_var_value() function returns 0 upon success
+** and 1 in case of malloc(3) failure. When returning 1, the
+** entire environment is destroyed.
