cairo_version ()

int                 cairo_version                       (void);

Returns the version of the cairo library encoded in a single integer as per CAIRO_VERSION_ENCODE. The encoding ensures that later versions compare greater than earlier versions.

A run-time comparison to check that cairo's version is greater than or equal to version X.Y.Z could be performed as follows:

if (cairo_version() >= CAIRO_VERSION_ENCODE(X,Y,Z)) {...}

cairo_version_string ()

const char*         cairo_version_string                (void);

Returns the version of the cairo library as a human-readable string of the form "X.Y.Z".
