rw_equal() [4/4]

template<class T >

int rw_equal ( T  x, T  y  )

inline

Compares two values of the same type for equality.

Parameters

x	The left hand side of the comparison.
y	The right hand side of the comparison.

Returns

Returns 1 if the the values are the same, 0 otherwise.

Definition at line 153 of file rw_valcmp.h.

rw_fltcmp()

_TEST_EXPORT int rw_fltcmp	(	float	x,
		float	y
	)

Compares two floating point numbers for equality.

Parameters

x	The left hand side of the comparison.
y	The right hand side of the comparison.

Returns

Returns a negative value, 0, or a positive value, depending on whether the first number is less than, equal to, or greater than the second number. The magnitude of the returned value indicates the number of distinct values representable in the type of the number between the two arguments.

template<class T , class U >

int rw_valcmp ( const T *  buf1, const U *  buf2, _RWSTD_SIZE_T  nelems, int  flags = 0  )

inline

Compares the contents of two arrays of objects of integral types, possibly of different sizes, for equality, in a strncmp/memcmp way.

Parameters

buf1	Pointer to an array of 0 or more objects of integral type.
buf2	Pointer to an array of 0 or more objects of integral type.
nelems	The maximum number of elements to compare.
flags	Bitmap of flags that determine how the objects are compared.

Returns

Returns -1, 0, or +1, depending on whether the first array is less than, equal to, or greater than the second array.
