A UParseError struct is used to returned detailed information about parsing errors.
Basic definitions for ICU, for both C and C++ APIs.
UErrorCode
Standard ICU4C error code type, a substitute for exceptions.
@ U_UNSUPPORTED_ERROR
Requested operation not supported in current context.
#define U_SUCCESS(x)
Does the error code indicate success?
#define U_I18N_API
Set to export library symbols from inside the i18n library, and to import them from outside.
