SIO-Command-$CA-Base64-Decode-Length
This is a command for Device $70 - The FujiNet Device itself (see SIO-Commands-for-Device-ID-$70).
Base64 Decode Length ($CA)
Description
This function is used to return the total size of the base64 encoded output. The resulting value is 32-bits (4 bytes) wide. Little-endian.
Firmware version required: 1.1 (2023.08.22) +
Parameters
| DCB | Value |
|---|---|
| DDEVIC | $70 |
| DUNIT | $01 |
| DCOMND | $CA |
| DSTATS | $40 |
| DBUF | a 4-byte buffer for the length |
| DTIMLO | $03 |
| DBYT | 4 |
| DAUX1 | 0 |
| DAUX2 | 0 |
Examples
CC65

OS.dcb.dbuf = len;
OS.dcb.dtimlo = BASE64_TIMEOUT;
OS.dcb.dbyt = sizeof(unsigned long);
OS.dcb.daux = 0;
siov();
return OS.dcb.dstats; // Return SIO error or success.
