Fast swap for C, any types to any types (gcc required), use only the header file fswap.h.

A functional combine producing swap objects of any types.

• Automatic calculation of the size of the item to be exchanged (swapped)
• Check the dimension of both elements.
• Checking the identity of both elements.
• High speed of data processing.
• Support C99 and above.

Using

To connect to your project, you need to declare a one header file:

#include "fswap.h"

Call swap method:

/* obj1, obj2 - any C types. */
__swap_fast(obj1, obj2);

Add new types

If you use own structures in an array format, you will need to add their description to fswap.h, example:

 __builtin_choose_expr( \
   __builtin_types_compatible_p(__typeof__(A), struct my_struct[]), __swap_p(A, B, sizeof(A), sizeof(B)), \
