Function Documentation

u_getVersion()

U_CAPI void u_getVersion

(

UVersionInfo

versionArray

)

Gets the ICU release version.

The version array stores the version information for ICU. For example, release "1.3.31.2" is then represented as 0x01031F02. Definition of this function lives in putil.c

Parameters

versionArray

the version # information, the result will be filled in

Stable:

ICU 2.0

u_versionFromString()

U_CAPI void u_versionFromString	(	UVersionInfo	versionArray,
		const char *	versionString
	)

Parse a string with dotted-decimal version information and fill in a UVersionInfo structure with the result.

Definition of this function lives in putil.c

Parameters

versionArray	The destination structure for the version information.
versionString	A string with dotted-decimal version information, with up to four non-negative number fields with values of up to 255 each.

Stable:

ICU 2.4

u_versionFromUString()

U_CAPI void u_versionFromUString	(	UVersionInfo	versionArray,
		const UChar *	versionString
	)

Parse a Unicode string with dotted-decimal version information and fill in a UVersionInfo structure with the result.

Definition of this function lives in putil.c

Parameters

versionArray	The destination structure for the version information.
versionString	A Unicode string with dotted-decimal version information, with up to four non-negative number fields with values of up to 255 each.

Stable:

ICU 4.2

u_versionToString()

U_CAPI void u_versionToString	(	const UVersionInfo	versionArray,
		char *	versionString
	)

Write a string with dotted-decimal version information according to the input UVersionInfo.

Definition of this function lives in putil.c

Parameters

versionArray	The version information to be written as a string.
versionString	A string buffer that will be filled in with a string corresponding to the numeric version information in versionArray. The buffer size must be at least U_MAX_VERSION_STRING_LENGTH.

Stable:
