Function

Pango.version_check

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

Parameters

`required_major`	`int`
	the required major version.
`required_minor`	`int`
	the required minor version.
`required_micro`	`int`
	the required major version.
