## Detailed Description

Version information.

Definition in file svn_version.h.

## Define Documentation

#define SVN_VER_LIBRARY SVN_VER_MAJOR

Deprecated:
  Provided for backward compatibility with the 1.0 API.

Definition at line 81 of file svn_version.h.

#define SVN_VER_MAJOR 1

Major version number.

Modify when incompatible changes are made to published interfaces.

Definition at line 58 of file svn_version.h.

#define SVN_VER_MICRO SVN_VER_PATCH

Deprecated:
  Provided for backward compatibility with the 1.0 API.

Definition at line 78 of file svn_version.h.

#define SVN_VER_MINOR 7

Minor version number.

Modify when new functionality is added or new interfaces are defined, but all changes are backward compatible.

Definition at line 65 of file svn_version.h.

#define SVN_VER_NUM

Value:

    APR_STRINGIFY(SVN_VER_MAJOR) \
                               "." APR_STRINGIFY(SVN_VER_MINOR) \
                               "." APR_STRINGIFY(SVN_VER_PATCH)

Version number.

Definition at line 129 of file svn_version.h.

#define SVN_VER_NUMTAG ""

Number tag: a string describing the version.

This tag is used to generate a version number string to identify the client and server in HTTP requests, for example. It must not contain any spaces. This value remains "-dev" in the repository.

When rolling a tarball, we automatically replace this text with "" for final releases; in prereleases, it becomes "-alpha1, "-beta1", etc., as appropriate.

Always change this at the same time as SVN_VER_TAG.

Definition at line 112 of file svn_version.h.

#define SVN_VER_PATCH 8

Patch number.

Modify for every released patch.

Since:
  New in 1.1.

Definition at line 74 of file svn_version.h.

#define SVN_VER_REVISION 1419691

Revision number: The repository revision number of this release.

This constant is used to generate the build number part of the Windows file version. Its value remains 0 in the repository.

When rolling a tarball, we automatically replace it with what we guess to be the correct revision number.

Definition at line 123 of file svn_version.h.

#define SVN_VER_TAG " (r1419691)"

Version tag: a string describing the version.

This tag remains " (dev build)" in the repository so that we can always see from "svn --version" that the software has been built from the repository rather than a "blessed" distribution.

When rolling a tarball, we automatically replace this text with " (r1234)" (where 1234 is the last revision on the branch prior to the release) for final releases; in prereleases, it becomes " (Alpha 1)", " (Beta 1)", etc., as appropriate.

Always change this at the same time as SVN_VER_NUMTAG.

Definition at line 97 of file svn_version.h.

#define SVN_VERSION_BODY

Value:

    SVN_VERSION_DEFINE(versioninfo);              \
      return &versioninfo

Generate the implementation of a version query function.

Since:
  New in 1.1.

Definition at line 182 of file svn_version.h.

#define SVN_VERSION_DEFINE | ( | name |  | ) |

Value:

    static const svn_version_t name = \
        { \
          SVN_VER_MAJOR, \
          SVN_VER_MINOR, \
          SVN_VER_PATCH, \
          SVN_VER_NUMTAG \
        } \

Define a static svn_version_t object.

Since:
  New in 1.1.

Definition at line 168 of file svn_version.h.

## Typedef Documentation

typedef struct svn_version_checklist_t svn_version_checklist_t

An entry in the compatibility checklist.

See also:
  svn_ver_check_list()

Since:
  New in 1.1.

typedef const svn_version_t*(* svn_version_func_t)(void)

Type of function returning library version.

Since:
  New in 1.6.

Definition at line 246 of file svn_version.h.

## Function Documentation

const svn_version_t* svn_subr_version | ( | void |  | ) |

Get libsvn_subr version information.

Since:
  New in 1.1.

svn_error_t* svn_ver_check_list | ( | const svn_version_t * | my_version,
|  | const svn_version_checklist_t * | checklist |
| ) |  |  |

Perform a series of version compatibility checks.

Checks if my_version is compatible with each entry in checklist. checklist must end with an entry whose label is `NULL`.

See also:
  svn_ver_compatible()

Since:
  New in 1.1.

svn_boolean_t svn_ver_compatible | ( | const svn_version_t * | my_version,
|  | const svn_version_t * | lib_version |
| ) |  |  |

Check library version compatibility.

Return TRUE if the client's version, given in my_version, is compatible with the library version, provided in lib_version.

This function checks for version compatibility as per our guarantees, but requires an exact match when linking to an unreleased library. A development client is always compatible with a previous released library.

Since:
  New in 1.1.

svn_boolean_t svn_ver_equal | ( | const svn_version_t * | my_version,
|  | const svn_version_t * | lib_version |
| ) |  |  |

Check if my_version and lib_version encode the same version number.

Since:
  New in 1.2.
