GLibGINT64_MODIFIER

The platform dependent length modifier for conversion specifiers for scanning and printing values of type #gint64 or #guint64. It is a string literal.

Some platforms do not support printing 64-bit integers, even though the types are supported. On such platforms G_GINT64_MODIFIER is not defined.

This is not necessarily the correct modifier for printing and scanning int64_t values, even though the in-memory representation is the same. Standard C macros like PRId64 and SCNd64 should be used for int64_t.
