Query Functions

Arguments

Name	Comments
pvci	The server connection handle.
outColumns	Array of column names. The last entry in the array must be NULL.
outValues	Array of the values of the columns.

vtc_retrieve_row retrieves the values from the fields in the top row. The names of the columns and their values are output in the outColumns and outValues arrays.

In C, outColumns and outValues are pointers to an array of strings.

All fields below the first row move up one row. For example, after the call, the values that were in the second row are in the first row, the values that were in the third row are in the second row, and so on. The last field of each column is cleared.

After using the output values, free the output buffers with vtc_free_list.

C# Language: No return value.

Parameterization
