public final Enum ArgFlag

Indicate that a structure parameter should be passed by value instead of by reference. This dereferences the parameter by prepending *. The parameter must not be NULL.

Indicate that GetPrimitiveArrayCritical() should be used instead of Get<PrimitiveType>ArrayElements() when transferring array of primitives from/to C. This is an optimization to avoid copying memory and must be used carefully. It is ok to be used in MoveMemory() and memmove() natives.

Indicate that the native parameter is a C# managed object.

Indicate that the associated C local variable for a native method parameter should be initialized with zeros.

Indicate that a native method parameter is an out only variable. This only makes sense if the parameter is a structure or an array of primitives. It is an optimization to avoid copying the java memory to C memory on the way in.

Indicate that a native method parameter is an in only variable. This only makes sense if the parameter is a structure or an array of primitives. It is an optimization to avoid copying the C memory from java memory on the way out.

Indicate that the parameter is a pointer.

Indicate that the parameter of a native method is the sentinel (last parameter of a variable argument C function). The generated code is always the literal NULL. Some compilers expect the sentinel to be the literal NULL and output a warning if otherwise.

Indicate that GetStringChars()should be used instead of GetStringUTFChars() to get the characters of a java.lang.String passed as a parameter to native methods.
