cbFileGetInfo()

Returns information about a streamer file. When cbFileAInScan() or cbFilePretrig() fills the streamer file, information is stored about how the data was collected (sample rate, channels sampled etc.). This function returns that information. Refer to board-specific information in the Universal Library User's Guide to determine if your board supports cbFileAInScan() and/or cbFilePretrig().
