Function
Pangoversion_check
since: 1.16
Declaration [src]
const char*
pango_version_check (
int required_major,
int required_minor,
int required_micro
)
Description [src]
Checks that the Pango library in use is compatible with the given version.
Generally you would pass in the constants PANGO_VERSION_MAJOR,
PANGO_VERSION_MINOR, PANGO_VERSION_MICRO as the three arguments
to this function; that produces a check that the library in use at
run-time is compatible with the version of Pango the application or
module was compiled against.
Compatibility is defined by two things: first the version
of the running library is newer than the version
required_major.required_minor.required_micro. Second
the running library must be binary compatible with the
version required_major.required_minor.required_micro
(same major version.)
For compile-time version checking use PANGO_VERSION_CHECK().
Available since: 1.16
