Detailed Description

Basic definitions for ICU, for both C and C++ APIs.

This file defines basic types, constants, and enumerations directly or indirectly by including other header files, especially utf.h for the basic character and string definitions and umachine.h for consistent integer and other types.

Definition in file utypes.h.

Macro Definition Documentation

◆ NULL

#define NULL   ((void *)0)

Define NULL if necessary, to nullptr for C++ and to ((void *)0) for C.

Stable:
ICU 2.0

Definition at line 188 of file utypes.h.

◆ U_COMBINED_IMPLEMENTATION

#define U_COMBINED_IMPLEMENTATION   1

Set to export library symbols from inside the ICU library when all of ICU is in a single library.

This can be set as a compiler option while building ICU, and it needs to be the first one tested to override U_COMMON_API, U_I18N_API, etc.

Stable:
ICU 2.0

Definition at line 295 of file utypes.h.

◆ U_COMMON_API

#define U_COMMON_API   U_EXPORT

Set to export library symbols from inside the common library, and to import them from outside.

Stable:
ICU 2.0

Definition at line 300 of file utypes.h.

◆ U_DATA_API

#define U_DATA_API   U_EXPORT

Set to export library symbols from inside the stubdata library, and to import them from outside.

Stable:
ICU 3.0

Definition at line 299 of file utypes.h.

◆ U_DATE_MAX

#define U_DATE_MAX   DBL_MAX

Maximum UDate value.

Stable:
ICU 4.8

Definition at line 218 of file utypes.h.

◆ U_DATE_MIN

#define U_DATE_MIN   -U_DATE_MAX

Minimum UDate value.

Stable:
ICU 4.8

Definition at line 224 of file utypes.h.

◆ U_FAILURE

#define U_FAILURE (   x)    ((x)>U_ZERO_ERROR)

Does the error code indicate a failure?

Stable:
ICU 2.0

Definition at line 717 of file utypes.h.

◆ U_HIDE_DRAFT_API

#define U_HIDE_DRAFT_API   1

Define this to 1 to request that draft API be "hidden".

API visibility control

Internal:
Do not use. This API is for internal use only.

Definition at line 84 of file utypes.h.

◆ U_HIDE_INTERNAL_API

#define U_HIDE_INTERNAL_API   1

Define this to 1 to request that internal API be "hidden".

Internal:
Do not use. This API is for internal use only.

Definition at line 87 of file utypes.h.

◆ U_I18N_API

#define U_I18N_API   U_EXPORT

Set to export library symbols from inside the i18n library, and to import them from outside.

Stable:
ICU 2.0

◆ U_ICUDATA_ENTRY_POINT

#define U_ICUDATA_ENTRY_POINT   U_DEF2_ICUDATA_ENTRY_POINT(U_ICU_VERSION_MAJOR_NUM,U_LIB_SUFFIX_C_NAME)

U_ICU_ENTRY_POINT is the name of the DLL entry point to the ICU data library.

Defined as a literal, not a string. Tricky Preprocessor use - ## operator replaces macro parameters with the literal string from the corresponding macro invocation, before other macro substitutions. Need a nested #defines to get the actual version numbers rather than the literal text U_ICU_VERSION_MAJOR_NUM into the name. The net result will be something of the form #define U_ICU_ENTRY_POINT icudt19_dat

Stable:
ICU 2.4

Definition at line 156 of file utypes.h.

◆ U_ICUDATA_NAME

#define U_ICUDATA_NAME   "icudt" U_ICU_VERSION_SHORT U_ICUDATA_TYPE_LETTER

A single string literal containing the icudata stub name.

i.e. 'icudt18e' for ICU 1.8.x on EBCDIC, etc..

Stable:
ICU 2.0

Definition at line 139 of file utypes.h.

◆ U_ICUDATA_TYPE_LETTER

#define U_ICUDATA_TYPE_LETTER   "l"

  • b for big-endian, ASCII-family platforms
  • l for little-endian, ASCII-family platforms

Typedef Documentation

Stable:
ICU 2.0

Definition at line 203 of file utypes.h.

◆ UErrorCode

typedef enum UErrorCode UErrorCode

Standard ICU4C error code type, a substitute for exceptions.

Initialize the UErrorCode with U_ZERO_ERROR, and check for success or failure using U_SUCCESS() or U_FAILURE():

UErrorCode errorCode = U_ZERO_ERROR;
// call ICU API that needs an error code parameter.
if (U_FAILURE(errorCode)) {
    // An error occurred. Handle it here.
}

C++ code should use icu::ErrorCode, available in unicode/errorcode.h, or a suitable subclass.

For more information, see: https://unicode-org.github.io/icu/userguide/dev/codingguidelines#details-about-icu-error-codes

Note: By convention, ICU functions that take a reference (C++) or a pointer (C) to a UErrorCode first test:

if (U_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.

Stable:
ICU 2.0

Enumeration Type Documentation

◆ UErrorCode

enum UErrorCode

Standard ICU4C error code type, a substitute for exceptions.

Initialize the UErrorCode with U_ZERO_ERROR, and check for success or failure using U_SUCCESS() or U_FAILURE():

UErrorCode errorCode = U_ZERO_ERROR;
// call ICU API that needs an error code parameter.
if (U_FAILURE(errorCode)) {
    // An error occurred. Handle it here.
}

C++ code should use icu::ErrorCode, available in unicode/errorcode.h, or a suitable subclass.
