SRV_ROWSENT The number of rows already sent by srvproc for the current set of results.

Is a pointer to an int variable that contains the length of the returned field value. If len is NULL, the length of the string is not returned.

Returns

A pointer to a null-terminated string containing the current value for the specified field in the SRV_PROC structure. If the field is empty, a valid pointer to an empty string is returned and len contains 0. If the field is unknown, NULL is returned and len contains the value -1.
