SD error codes

[Utopia]

While testing  my SD card, I had to expose the error code provided by the Sd2Card 'card' in the class SDClass (\SD\SD.h)

Code: [Select]

class SDClass {
...
 Sd2Card card;
...
public:
int error(void)
{
 return card.errorCode();
}

I'd like to suggest this be added to the code, since others might want to know what the error code is when their SD card fails.

Sounds like a good idea, if all errorcodes are documented, what they mean, cq how to solve (could be in a separate txt file, not in the SDclass)

currently, they are in \libraries\SD\utility\Sd2Card.h starting from line 95, so even the error function as it stands would provide some use/help

In the beginning I used error codes for debug in SdFat.  They have not been the same from version to version.

Error codes have become useful for diagnosing hardware problems so I plan to implement a error code to text function in a future version of SdFat.

SD.h is a wrapper for an old version of SdFat so this won't help SD.h users.
