Macro Definition Documentation

#define IL_DATE_FAILURE

(

x

)

Tests a IlDateErrorCode value for failure.

Returns

1 if the value is an error, 0 otherwise

#define IL_DATE_SUCCESS

(

x

)

Tests a IlDateErrorCode value for success.

Returns

1 if the value is not error, 0 otherwise

Enumeration Type Documentation

enum IlDateErrorCode

Error code to replace exception handling so that the code is compatible with all C++ compilers, and to use the same mechanism for C and C++.

Functions that take a reference (C++) or a pointer (C) to a IlDateErrorCode first test:

if (IL_DATE_FAILURE(errorCode)) {
  return immediately;
}

So that in a chain of such functions the first one that sets an error code causes the following ones to not perform any operations.
Error codes should be tested using IL_DATE_FAILURE() and IL_DATE_SUCCESS().

Enumerator
IL_DATE_ERROR_INFO_START	Start of information results (semantically successful).
IL_DATE_USING_FALLBACK_ERROR	A resource bundle lookup returned a fallback result (not an error).
IL_DATE_USING_DEFAULT_ERROR	A resource bundle lookup returned a result from the root locale (not an error).
IL_DATE_SAFECLONE_ALLOCATED_ERROR	A SafeClone operation required allocating memory (informational only).
IL_DATE_ERROR_INFO_LIMIT	This must always be the last warning value to indicate the limit for IlDateErrorCode warnings (last warning code +1).
IL_DATE_ZERO_ERROR	No error, no warning.
IL_DATE_ILLEGAL_ARGUMENT_ERROR	Start of codes indicating failure.
IL_DATE_INTERNAL_PROGRAM_ERROR	Indicates a bug in the library code.
IL_DATE_MEMORY_ALLOCATION_ERROR	Memory allocation error.
IL_DATE_PARSE_ERROR	Equivalent to Java ParseException.
IL_DATE_INVALID_CHAR_FOUND	In the Character conversion routines: Invalid character or sequence was encountered.
IL_DATE_TRUNCATED_CHAR_FOUND	In the Character conversion routines: More bytes are required to complete the conversion successfully.
IL_DATE_ILLEGAL_CHAR_FOUND	In codeset conversion: a sequence that does NOT belong in the codepage has been encountered.
IL_DATE_INVALID_TABLE_FORMAT	Conversion table file found, but corrupted.
IL_DATE_INVALID_TABLE_FILE	Conversion table file not found.
IL_DATE_BUFFER_OVERFLOW_ERROR	A result would not fit in the supplied buffer.
IL_DATE_UNSUPPORTED_ERROR	Requested operation not supported in current context.
IL_DATE_RESOURCE_TYPE_MISMATCH	An operation is requested over a resource that does not support it.
IL_DATE_ILLEGAL_ESCAPE_SEQUENCE	ISO-2022 illegal escape sequence.
IL_DATE_UNSUPPORTED_ESCAPE_SEQUENCE	ISO-2022 unsupported escape sequence.
IL_DATE_NO_SPACE_AVAILABLE	No space available for in-buffer expansion for Arabic shaping.
IL_DATE_ERROR_LIMIT	This must always be the last value to indicate the limit for IlDateErrorCode (last error code +1).
