srv_setcoldata (Extended Stored Procedure API)
Specifies the current address for a column's data.
int srv_setcoldata ( SRV_PROC * srvproc , int column , void * data );
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.
Indicates the number of the column the address is being specified for. Columns are numbered beginning with 1.
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.
SUCCEED or FAIL.
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.
