SWAP

NOTE: This library is currently under maintenance and should not be used.

The SWAP Macro can be used to swap to variables of the same data type in memory. This Macro uses a _Generic operator to determine the data types and the correct underlying function to use for the operation. If the user enters to mis-matched data types, this Macro will fail at compile time.

void SWAP(type a, type b)

Parameters

• a: The first variable to be swapped in memory

• b: The second variable to be swapped in memory

#include swap.h
#include print.h

int a = 5;
int b = 12;
PRINT("Before Swap");
PRINT("a = ", a);
PRINT("b = ", b);
SWAP(a, b)
PRINT("After Swap");
PRINT("a = ", a);
PRINT("b = ", b);

>> Before Swap
>> a = 5
>> b = 12
>> After Swap
>> a = 12
>> b = 5

The following functions can be used in place of the type generic SWAP Macro. These functions can be accessed via the swap.h file.

void swap_short(short int *a, short int *b)
void swap_ushort(unsigned short int *a, unsigned short int *b)
void swap_int(int *a, int *b)
void swap_uint(unsigned int *a, unsigned int *b)
void swap_long(long int *a, long int *b)
void swap_ulong(unsigned long *a, unsigned long *b)
void swap llong(long long int *a, long long int *b)
void swap ullong(unsigned long long int *a, unsigned long long int *b)
void swap float(float *a, float *b)
void swap double(double *a, double *b)
void swap_ldouble(long double *a, long double *b)
void swap_char(char *a, char *b)
void swap_uchar(unsigned char *a, unsigned char *b)
void swap_bool(bool *a, bool *b)

#include swap.h
#include print.h

int a = 5;
int b = 12;
PRINT("Before Swap");
PRINT("a = ", a);
PRINT("b = ", b);
swap_int(&a, &b)
PRINT("After Swap");
PRINT("a = ", a);
PRINT("b = ", b);

>> Before Swap
>> a = 5
>> b = 12
>> After Swap
>> a = 12
>> b = 5
