viVPrintf − Converts, formats, and sends params to a device

SYNOPSIS

viVPrintf(ViSession vi, ViString writeFmt, ViVAList params);

Description

This function converts, formats, and sends params to the device as specified by the format string. This function is similar to viPrintf, except that the ViVAList parameters list provides the parameters rather than separate arg parameters.

vi An input parameter. Unique logical identifier to a session.

writeFmt An input parameter. The format string to apply to parameters in ViVAList. See viPrintf for description.

params An input parameter. A list containing the variable number of parameters on which the format string is applied. The formatted data is written to the specified device.

Return Values

VI_SUCCESS Parameters were successfully formatted.

VI_ERROR_INV_SESSION VI_ERROR_INV_OBJECT The given session or object reference is invalid (both are the same value).

VI_ERROR_IO Could not perform write function because of I/O error.
