AlazarRead

Function Syntax

U32 AlazarRead(HANDLE handle, U32 channelId, void * buffer, int elementSize, long record, long transferOffset, U32 transferLength)

Read all of part of a record from on-board memory to host memory (RAM).

The record must be less than 2,147,483,648 samples long.

Return

ApiSuccess upon success, or an error code. See RETURN_CODE for more detailed information.

Note

AlazarRead() is part of the single-port API, it cannot be used in a dual-port context.

Remark

AlazarRead() can transfer segments of a record. This may be useful if a full record is too large to transfer as a single clock, or if only part of a record is of interest.

Remark

Use AlazarReadEx() To transfer records with more than 2 billion samples.

Parameters

• handle: Board handle
• channelId: The channel identifier of the record to read.
• buffer: Buffer to receive sample data
• elementSize: Number of bytes per sample
• record: Index of the record to transfer (1-indexed)
• transferOffset: The offset, in samples, from the trigger position in the record, of the first sample to transfer.
• transferLength: The number of samples to transfer.
