HEreport can then be used to give a more case-specific description of the error. Only one additional annotation can be attached to each error report. The format argument must conform to the string specification requirements of printf . Purpose Returns the error message associated with error code.
Return value Returns a pointer to a string associated with the error code if successful.
Description Returns a text description of the given error code. If a defined text description cannot be found a generic default message is returned.
