Detailed Description

Basic types for the platform.

This file used to be generated by autoconf/configure. Starting with ICU 49, platform.h is a normal source file, to simplify cross-compiling and working with non-autoconf/make build systems.

When a value in this file does not work on a platform, then please try to derive it from the U_PLATFORM value (for which we might need a new value constant in rare cases) and/or from other macros that are predefined by the compiler or defined in standard (POSIX or platform or compiler) headers.

As a temporary workaround, you can add an explicit #define for some macros before it is first tested, or add an equivalent -D macro definition to the compiler's command line.

Note: Some compilers provide ways to show the predefined macros. For example, with gcc you can compile an empty .c file and have the compiler print the predefined macros with

gcc -E -dM -x c /dev/null | sort

(You can provide an actual empty .c file rather than /dev/null. -x c++ is for C++.)

Macro Definition Documentation

◆ __has_attribute

#define __has_attribute (   x)    0

Compiler and environment features If the compiler is not gcc, then U_GCC_MAJOR_MINOR == 0.

Internal:

Definition at line 468 of file platform.h.

◆ U_ASCII_FAMILY

#define U_ASCII_FAMILY   0

U_CHARSET_FAMILY is equal to this value when the platform is an ASCII based platform.

Character data types

Stable:
ICU 2.0

Definition at line 552 of file platform.h.

◆ U_CALLCONV

#define U_CALLCONV   U_EXPORT2

Similar to U_CDECL_BEGIN/U_CDECL_END, this qualifier is necessary in callback function typedefs to make sure that the calling convention is compatible.

This is only used for non-ICU-API functions. When a function is a public ICU API, you must use the U_CAPI and U_EXPORT2 qualifiers.

Please note, you need to use U_CALLCONV after the *.

NO : "static const char U_CALLCONV *func( . . . )" YES: "static const char* U_CALLCONV func( . . . )"

Stable:
ICU 2.0

Definition at line 848 of file platform.h.

◆ U_CALLCONV_FPTR

#define U_CALLCONV_FPTR

Similar to U_CALLCONV, but only used on function pointers.

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

Definition at line 859 of file platform.h.

◆ U_CHARSET_FAMILY

#define U_CHARSET_FAMILY   U_ASCII_FAMILY

These definitions allow to specify the encoding of text in the char data type as defined by the platform and the compiler. It is enough to determine the code point values of "invariant characters", which are the ones shared by all encodings that are in use on a given platform.

Those "invariant characters" should be all the uppercase and lowercase latin letters, the digits, the space, and "basic punctuation". Also, '\n', '\r', '\t' should be available.

The list of "invariant characters" is:

A-Z a-z 0-9 SPACE " % &amp; ' ( ) * + , - . / : ; < = > ? _


(52 letters + 10 numbers + 20 punc/sym/space = 82 total)

This matches the IBM Syntactic Character Set (CS 640).

In other words, all the graphic characters in 7-bit ASCII should be safely accessible except the following:

'\' <backslash>
'[' <left bracket>
']' <right bracket>
'{' <left brace>
'}' <right brace>
'^' <circumflex>
'~' <tilde>
'!' <exclamation mark>
'#' <number sign>
'|' <vertical line>
'$' <dollar sign>
'@' <commercial at>
'`' <grave accent>
Stable:
ICU 2.0

Definition at line 609 of file platform.h.

◆ U_CHARSET_IS_UTF8

#define U_CHARSET_IS_UTF8   0

Hardcode the default charset to UTF-8.

If this is set to 1, then

  • ICU will assume that all non-invariant char*, StringPiece, std::string etc. contain UTF-8 text, regardless of what the system API uses
  • some ICU code will use fast functions like u_strFromUTF8() rather than the more general and more heavy-weight conversion API (ucnv.h)
  • ucnv_getDefaultName() always returns "UTF-8"
  • ucnv_setDefaultName() is disabled and will not change the default charset
  • static builds of ICU are smaller
  • more functionality is available with the UCONFIG_NO_CONVERSION build-time configuration option (see unicode/uconfig.h)
  • the UCONFIG_NO_CONVERSION build option in uconfig.h is more usable
Stable:
ICU 4.2

◆ U_CPLUSPLUS_VERSION

#define U_CPLUSPLUS_VERSION   0

0 if no C++; 1, 11, 14, ...

if C++. Support for specific features cannot always be determined by the C++ version alone.

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

◆ U_EBCDIC_FAMILY

#define U_EBCDIC_FAMILY   1

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

The U_PLATFORM macro defines the platform we're on.

We used to define one different, value-less macro per platform. That made it hard to know the set of relevant platforms and macros, and hard to deal with variants of platforms.

Starting with ICU 49, we define platforms as numeric macros, with ranges of values for related platforms and their variants. The U_PLATFORM macro is set to one of these values.

Historical note from the Solaris Wikipedia article: AT&T and Sun collaborated on a project to merge the most popular Unix variants on the market at that time: BSD, System V, and Xenix. This became Unix System V Release 4 (SVR4).

◆ UPRV_INCOMPLETE_CPP11_SUPPORT

#define UPRV_INCOMPLETE_CPP11_SUPPORT   (U_PLATFORM == U_PF_AIX || U_PLATFORM == U_PF_OS390 || U_PLATFORM == U_PF_SOLARIS )

This switch turns off ICU 60 NumberFormatter code.

By default, this switch is enabled on AIX and z/OS, which have poor C++11 support.

NOTE: This switch is intended to be temporary; see #13393.

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