The crcmod package is capable of generating C functions that can be compiled with a C or C++ compiler. This image is an example of how you can use this function as a subVI to calculate the CRC32 of a single file. Note that byte crc[] stack-allocates crc, so it goes away when the function returns; ie, officially is no good as a returned result. The latter is probably most used now, because among others it is the CRC generator for all network traffic verification and validation. Complete this form to generate a new CSR and private key. Discussion in 'Electrical Codes' started by Mule, Feb 16, 2012.
