Description

NOTE:
These functions are deprecated and will be removed in a future release. If you have concerns, open a ticket and provide feedback at https://supporttickets.intel.com/.

These functions compare first len elements of two strings pSrc1 and pSrc2. If all pairs of elements in the strings are equal, the function returns pResult = 0. If the pair of non-matching elements occurs in the i-th position, the function stops operation and returns pResult. The returned value is positive when pSrc1[i]> pSrc2[i] and negative when pSrc1[i]< pSrc2[i]. The comparison is case-insensitive.

The function ippsCompareIgnore operates with Unicode characters. The function ippsCompareIgnoreLatin operates with ASCII characters.

Code example shows how to use the function ippsCompareIgnoreCaseLatin_8u.

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.
