* @brief
|
|
* General exception class for all C++ exceptions in IDF.
|
|
*
|
|
* All throwing code in IDF should use either this exception directly or a sub-classes.
|
|
* An error from the underlying IDF function is mandatory. The idea is to wrap the orignal IDF error code to keep
|
|
* the error scheme partially compatible. If an exception occurs in a higher level C++ code not directly wrapping
|
|
* IDF functions, an appropriate error code reflecting the cause must be chosen or newly created.
