The garcon library provides version information, which could be used by developers to handle new API.
#define GARCON_CHECK_VERSION(major,minor,micro)
Checks the version of the garcon library.
|
the major version number. |
|
the minor version number. |
|
the micro version number. |
Returns : |
TRUE if the version of the garcon header files is
the same as or newer than the passed-in version. |
#define GARCON_MAJOR_VERSION 0
The major version number of the garcon library. Like garcon_major_version, but from the headers used at application compile time, rather than from the library linked against at application run time.
#define GARCON_MICRO_VERSION 0
The micro version number of the garcon library. Like garcon_micro_version, but from the headers used at application compile time, rather than from the library linked against at application run time.
#define GARCON_MINOR_VERSION 2
The minor version number of the garcon library. Like garcon_minor_version, but from the headers used at application compile time, rather than from the library linked against at application run time.
const gchar * garcon_check_version (guint required_major
,guint required_minor
,guint required_micro
);
Checks that the garcon
library in use is compatible with the given version. Generally you
would pass in the constants GARCON_MAJOR_VERSION,
GARCON_MINOR_VERSION and GARCON_MICRO_VERSION as the three
arguments to this function; that produces a check that the library
in use is compatible with the version of
garcon
the application was
compiled against.
Example 1. Checking the runtime version of the garcon library
const gchar *mismatch; mismatch = garcon_check_version (GARCON_VERSION_MAJOR, GARCON_VERSION_MINOR, GARCON_VERSION_MICRO); if (G_UNLIKELY (mismatch != NULL)) g_error ("Version mismatch: %s", mismatch);
|
the required major version. |
|
the required minor version. |
|
the required micro version. |
Returns : |
NULL if the library is compatible with the given version,
or a string describing the version mismatch. The returned
string is owned by the library and must not be freed or
modified by the caller. |
gchar * garcon_config_lookup (const gchar *filename
);
Looks for the filename in the users' config directory and then the system config directories.
|
relative filename of the config resource. |
Returns : |
the absolute path to the first file in the search path,
that matches filename or NULL if no such
file or directory could be found. |
extern const guint garcon_major_version;
The major version number of the garcon library (e.g. in version 4.8.0 this is 4).
This variable is in the library, so represents the garcon library you have linked against. Contrast with the GARCON_MAJOR_VERSION macro, which represents the major version of the garcon headers you have included.
extern const guint garcon_micro_version;
The micro version number of the garcon library (e.g. in version 4.8.0 this is 0).
This variable is in the library, so represents the garcon library you have linked against. Contrast with the GARCON_MICRO_VERSION macro, which represents the micro version of the garcon headers you have included.
extern const guint garcon_minor_version;
The minor version number of the garcon library (e.g. in version 4.8.0 this is 8).
This variable is in the library, so represents the garcon library you have linked against. Contrast with the GARCON_MINOR_VERSION macro, which represents the minor version of the garcon headers you have included.
