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`` | [integer] the required major version.
``required.minor`` | [integer] the required minor version.
``required.micro`` | [integer] 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.
