Description

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

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.
