Specifies the current address for a column's data.
Sintassi
int srv_setcoldata (
SRV_PROC *
srvproc
,
int
column
,
void *
data
);
Arguments
- srvproc
Is a pointer to the SRV_PROC structure that is the handle for a particular client connection. The structure contains information the Extended Stored Procedure API library uses to manage communication and data between the application and the client.
- column
Indicates the number of the column the address is being specified for. Columns are numbered beginning with 1.
- data
Is a pointer for a column's data. Memory allocated for data should not be freed until the column data is replaced by another call to srv_setcoldata, or until srv_senddone is called.
Returns
SUCCEED or FAIL.
Osservazioni
Each column of the row must be defined first with srv_describe. Column data addresses are initially set with srv_describe. If the address of the column data changes, srv_setcoldata must be called to specify the new address of the data and srv_setcoldata must be called separately for each changed column.
Null data is represented by setting the column's length to 0 with srv_setcollen. The data address is then ignored.
