#define LITIRAL_CRC32

(

str

)

Value:

(QuasarAppUtils::calculateCrc32(str, sizeof(str) - 1))

LITIRAL_CRC32 This is a compile-time macro that calculates the crc32 hash of the string literal.

Parameters

str	This is the string literal that will be hashed.

Note

The trailing zero of the string literal is not included into the hash.
