## Macros

#define | U_COPYRIGHT_STRING_LENGTH 128
| Maximum length of the copyright string.
#define | U_MAX_VERSION_LENGTH 4
| An ICU version consists of up to 4 numbers from 0..255.
#define | U_VERSION_DELIMITER '.'
| In a string, ICU version fields are delimited by dots.
#define | U_MAX_VERSION_STRING_LENGTH 20
| The maximum length of an ICU version string.

## Typedefs

typedef uint8_t | UVersionInfo[U_MAX_VERSION_LENGTH]
| The binary form of a version on ICU APIs is an array of 4 uint8_t.

## Functions

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.
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.
U_CAPI void | u_versionToString (const UVersionInfo versionArray, char *versionString)
| Write a string with dotted-decimal version information according to the input UVersionInfo.
U_CAPI void | u_getVersion (UVersionInfo versionArray)
| Gets the ICU release version.

## Typedef Documentation

## UVersionInfo

typedef uint8_t UVersionInfo[U_MAX_VERSION_LENGTH]

## 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.

## 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.
