Equal

Compares two string of the fixed length for equality.

Syntax

IppStatus ippsEqual_8u(const Ipp8u* pSrc1, const Ipp8u* pSrc2, int len, int* pResult);

IppStatus ippsEqual_16u(const Ipp16u* pSrc1, const Ipp16u* pSrc2, int len, int* pResult);

Parameters

pSrc1

Pointer to the first source string.

pSrc2

Pointer to the second source string.

len

Maximum number of elements to be compared.

pResult

Pointer to the result.

Description

The function ippsEqual is declared in the ippch.h file. This function compares first len elements of two strings pSrc1 and pSrc2. Each element of the first string is compared with the corresponding element of the second string. When the first pair of non-matching elements is found, the function stops operation and stores 0 in pResult. If the strings are equal, the function stores 1 in pResult. The comparison is case-sensitive.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error condition if at least one of the specified pointers is NULL.

ippStsLengthErr

Indicates an error condition if len is negative.
