Purpose
Returns the default format or the format set in the contract function by a previous call to FNC_TblOpSetFormat.
Syntax
void FNC_TblOpGetFormat(char *attribute, int streamno, Stream_Direction_en direction, void *outValue, int outSize);
- char *attribute
- the format attribute to be retrieved. Currently, the only possible value is "RECFMT".
- int streamno
- the stream number.
- Stream_Direction_en direction
- the stream direction: 'R' or 'W'.
- void *outValue
- the buffer where the format attribute value is returned.
- int outSize
- the size in bytes of the outValue buffer.
Usage Notes
Format attribute "RECFMT" defines the input/output record format and has the following two possible values:
typedef enum
{
INDICFMT1 = 1, /* IndicData with row separator sentinels */
INDICBUFFMT1 = 2 /* IndicData with NO row or partition separator sentinels */
} Stream_Fmt_en;
When format attribute is "RECFMT", buffer outvalue should be of size sizeof(Stream_Fmt_en) and the attribute value returned would be INDICFMT1 (IndicData with row separator sentinels) or INDICBUFFMT1 (IndicData with no row or partition separator sentinels). Memory must be allocated for buffer outvalue before FNC_TblOpGetFormat is called and released after the buffer is no longer needed.
