## ◆ XAPIAN_AT_LEAST

#define XAPIAN_AT_LEAST | ( |  | A,
|  |  | B,
|  |  | C
| ) |  |

Value:
(XAPIAN_MAJOR_VERSION > (A) || \
(XAPIAN_MAJOR_VERSION == (A) && \
(XAPIAN_MINOR_VERSION > (B) || \
(XAPIAN_MINOR_VERSION == (B) && XAPIAN_REVISION >= (C)))))
XAPIAN_MAJOR_VERSION
#define XAPIAN_MAJOR_VERSION

XAPIAN_AT_LEAST(A,B,C) checks for xapian-core >= A.B.C - use like so:

#if XAPIAN_AT_LEAST(1,4,2)
/* Code needing features needing Xapian >= 1.4.2. */
#endif

Added in Xapian 1.4.2.

## ◆ XAPIAN_MAJOR_VERSION

#define XAPIAN_MAJOR_VERSION 1

The major component of the Xapian version.

E.g. for Xapian 1.0.14 this would be: 1

## ◆ XAPIAN_MINOR_VERSION

#define XAPIAN_MINOR_VERSION 4

The minor component of the Xapian version.

E.g. for Xapian 1.0.14 this would be: 0

## ◆ XAPIAN_REVISION

#define XAPIAN_REVISION 11

The revision component of the Xapian version.

E.g. for Xapian 1.0.14 this would be: 14
