c++ - Atomic increment on mac OS X -

-

I have googled for atomic increments and decrease operators on Mac OS X and found "OSAtomic.h" but it seems That you can use it only in the kernel space.

told me on a cross-platform, in which they use assembly or mutes on OS X (as far as I am among the ifdefs).

Is there nothing like InterlockedDecrement or atomic_dec () on OS X?

Do you think OSAtmic is the only kernel space? The following compile and works fine. 

  #include & lt; Libkern / OSAtomic.h> # Include & lt; Stdio.h & gt; Int main (int argc, char ** argv) {int32_t foo = 1; OSAtomicDecrement32 (& amp; foo); Printf ("% d \ n", foo); Return 0; }

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
