gwyversion

gwyversion — Version information

Functions

gint gwy_version_major ()
gint gwy_version_minor ()
const gchar * gwy_version_string ()

Types and Values

#define GWY_VERSION_MAJOR
#define GWY_VERSION_MINOR
#define GWY_VERSION_STRING

Includes

#include <libgwyddion/gwyddion.h>

Description

Macros like GWY_VERSION_MAJOR can be used for compile-time version checks, that is they tell what version a module or app is being compiled or was compiled with.

On the other hand functions like gwy_version_major() can be used to run-time version checks and they tell what version a module or app was linked or is running with.

Functions

gwy_version_major ()

gint
gwy_version_major (void);

Gets the major version of Gwyddion.

If the version is 1.99.7.20060604, this function returns 1.

Returns

The major version.

gwy_version_minor ()

gint
gwy_version_minor (void);

Gets the minor version of Gwyddion.

If the version is 1.99.7.20060604, this function returns 99.

Returns

The minor version.

gwy_version_string ()

const gchar *
gwy_version_string (void);

Gets the full Gwyddion version as a string.

If the version is 1.99.7.20060604, this function returns "1.99.7.20060604".

This is the only method to get finer version information than major.minor. However, only development versions use finer versioning than major.minor therefore a module or app requiring such information is probably broken anyway. A meaningful use is to advertise the version of Gwyddion your app runs with.

Returns

The full version as a constant string.

Types and Values

GWY_VERSION_MAJOR

#define GWY_VERSION_MAJOR 2

Expands to the major version of Gwyddion as a number.

If the version is 1.99.7.20060604, this macro is defined as 1.

GWY_VERSION_MINOR

#define GWY_VERSION_MINOR 55

Expands to the minor version of Gwyddion as a number.

If the version is 1.99.7.20060604, this macro is defined as 99.

GWY_VERSION_STRING

#define GWY_VERSION_STRING "2.55"

Expands to the full Gwyddion version as a string.

If the version is 1.99.7.20060604, this macro is defined as "1.99.7.20060604".

See gwy_version_string() for caveats.
