This version of gd_getdata(3) uses a 64-bit offset type (gd_off64_t), regardless of the size of off_t. This function is only guaranteed to be available if GD_64BIT_API is defined before including getdata.h.

If off_t is a 64-bit type, this function will the same as gd_getdata(3). Otherwise, gd_getdata(3) will be a version of this function which uses a 32-bit off_t.
