CallingConvention

A function mapper which maps from java function names to native function names.

Function calls should NOT save the errno/last error after the call. This option can be overridden on individual methods by use of the jnr.ffi.annotations.SaveError annotation.

Load the library into memory immediately, instead of lazily loading it

Relevant for GNU/Linux Platform.Linux only Prefer custom paths over system paths when loading a library, even if the custom path has a lower version. By default JNR-FFI will choose the library of the desired name with the highest version, whether in the custom paths or the system default paths. This can be a problem if you are distributing your own library for example libfoo.so and the system paths happen to have a libfoo.so.4 for example, in which case JNR-FFI will prefer the higher version despite your explicit custom paths. By using this option, JNR-FFI will know to prefer the custom paths, even if they have a lower version, this ensures consistent behaviors across environments.

Function calls should save the errno/last error after the call. This option can be overridden on individual methods by use of the jnr.ffi.annotations.IgnoreError annotation.
