pangoVersionCheck {RGtk2}R Documentation

pangoVersionCheck

Description

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.

Usage

pangoVersionCheck(required.major, required.minor, required.micro)

Arguments

required.major

the required major version.

required.minor

the required minor version.

required.micro

the required major version.

Details

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 pangoVersionCheck(). Since 1.16

Value

[char] NULL if the Pango library is compatible with the given version, or a string describing the version mismatch.
