       odbx_field_length - Returns the length of a field value


       #include <opendbx/api.h>

       unsigned long odbx_field_length (odbx_result_t* result, unsigned long pos);


       odbx_field_length()  returns  the length of the field value in bytes. The field is part of
       the current row which was  retrieved  by  the  latest  call  to  odbx_row_fetch()  and  is
       specified by the column index given by pos.

       The  result  parameter  required  by  this function must be a valid result set returned by
       odbx_result() and must not has been feed to odbx_result_finish() before.

       Valid column indices for the requested column provided via pos start  with  zero  and  end
       with the value returned by odbx_column_count() minus one.


       The  odbx_field_length()  function  provides the number of bytes of the specified field to
       the caller. If the field value consists of character data, the  returned  length  will  be
       without  the  terminating zero character. For binary values the exact size of the block as
       stored in the database is returned.


       This function will also return zero if the result parameter is invalid or if the value  of
       pos is out of range.
