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
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.
