Detailed Description

Indicates an error in the low level I/O software/firmware/hardware used in the device servers.

Each rdaIOError exception provides several kinds of information:

• a string describing the error.
• a string that identifies the error category. This is typically a name of the I/O package or driver which emitted the error. For example, "PS-GM", "SL-EQUIP", "CAMAC", "GPIB", etc.. Possible values of the category string shall be described in the device server documentation.
• an integer error code that is specific to each category. Normally this will be the actual error code returned by the underlying I/O package.
• an optional rdaData object which can be used to provide additional error information.
