Generated on Wed Mar 18 14:12:15 2009, by pycrc v0.7, http://www.tty1.net/pycrc/ using the configuration: Width = 16 Poly = 0x8005 XorIn = 0x0000 ReflectIn = True XorOut = 0x0000 ReflectOut = True Algorithm = table-driven Direct = True
Modified 2009-03-16 not to include <stdint.h> as our Win32 environment appears not to have it; we're using GLib types, instead.
| #define CRC_ALGO_TABLE_DRIVEN 1 |
The definition of the used algorithm.
| typedef uint16_t crc16_plain_t |
The type of the CRC values.
This type must be big enough to contain at least 16 bits.
| WS_DLL_PUBLIC uint16_t crc16_8005_noreflect_noxor | ( | const uint8_t * | data, |
| uint64_t | data_len | ||
| ) |
Calculate the crc-16 (x^16 + x^15 + x^2 + 1) value for data. Note that this CRC is not equal to crc16_plain.
| data | Pointer to a buffer of data_len bytes. |
| data_len | Number of bytes in the data buffer. |
| long crc16_plain_reflect | ( | long | data, |
| size_t | data_len | ||
| ) |
Reflect all bits of a data word of data_len bytes.
| data | The data word to be reflected. |
| data_len | The width of data expressed in number of bits. |
| WS_DLL_PUBLIC crc16_plain_t crc16_plain_update | ( | crc16_plain_t | crc, |
| const unsigned char * | data, | ||
| size_t | data_len | ||
| ) |
Update the crc value with new data.
| crc | The current crc value. |
| data | Pointer to a buffer of data_len bytes. |
| data_len | Number of bytes in the data buffer. |
