Find string at UNICODE buffer using MEMCMP

[Kuluoz]

unsigned char *buffer =NULL;
char findstring = "cplusplus"

buffer = function_to_ADD(starting_address, size)

/* in this buffer size 1500. all the data are UNICODE.

for(uint32_t i=0;i<size;i++)
{
if(0 == memcmp((char*)buffer,findstring,strlen(findstring )))
/*after some condition */
}

in this part buffer have unicode string. findstring is ASCII .

How to i convert ascii to uncode and find findstring in buffer.i do not know how to check?
can anyone help me?

you don't want to convert ascii to unicode.

first, findstring is a single character, which cannot hold a string, so that assignment is not legal and should fail.

second, you should be using c++ strings:
string findstring = "cplusplus";

to make string objects unicode, read this:

once you set up your strings for unicode, you can search them with string.find() and you can compare with == operations.

Memcpy and memcmp are best avoided unless deep inside a very low level high performance code block.
