The result is returned in memory allocated using `palloc`. (You can use `pfree` to release the memory when you don't need it anymore.) ## Arguments **`HeapTuple row`** input row to be examined **`TupleDesc rowdesc`** input row description **`int colnumber`** column number (count starts at 1) ## Return Value Column value, or `NULL` if the column is null, `colnumber` is out of range (`SPI_result` is set to `SPI_ERROR_NOATTRIBUTE`), or no output function is available (`SPI_result` is set to `SPI_ERROR_NOOUTFUNC`).
