Data Update Functions

## Arguments

Name | Comments
--- | ---
pvci | The server connection handle.
columnName | The column name.
rowIndex | The row number. The first row has index 1.
incrValue | The amount to change the field value by. If incValue is negative, it is subtracted from the field value.
outValue | The new value of the field.

vtc_increment changes the value in the field by the amount passed in argument incrValue.

If the cell value cannot be converted to an integer or if there is no data in the cell, the cell value after the vtc_increment call is the `incrValue` argument value.

## Return Values

Returns 1 on success and 0 on failure.

## Parameterization

All string input arguments can be passed using standard parameterization.

## C Language Example

Copy code

    int rc = 0;
    int newValue = 0;

    // Increment Col1 row#1 by 1
    rc = vtc_increment(pvci, "Col1", 1, 1, &newValue);
