const char* odbx_field_value(
    odbx_result_t* result,
    unsigned long pos )

Description:

Returns the field value specified by "pos" of the current row. The value of "pos" must be in the range from 0 to odbx_column_count()-1. All values except binary objects are strings terminated by \0 but NULL is also a valid field value. Numbers have to be converted to their binary representation before arithmetic operations are allowed.

Parameters:

• result: Pointer to object created by odbx_result()
• pos: Column number in the current result set

Return values:

• Address of a string or binary object for the specified field
• NULL if the field is a NULL value, "result" is invalid or "pos" is out of range.
