Why use it
It provides direct, allocation-conscious access to the adler32 module. No exception-based error path is implied by the signature.

Function
Computes the adler32 checksum of a buffer, only reading bytes.
Declaration
Declaration
uint32_t adler32_bytes(uint8_t* buffer, unsigned length, uint32_t sum = 1)Computes the adler32 checksum of a buffer, only reading bytes.
| Parameter | Type | Meaning |
|---|---|---|
buffer | uint8_t * | The buffer to checksum. |
length | unsigned int | Value supplied for length. Keep referenced or pointed-to data valid for the complete call. |
sum | uint32_t | The previous sum to continue the checksum for. |
Returns: uint32_t — The adler32 checksum of the buffer.
Example
C++ example
#include "psyqo/adler32.hh"
// Assume these named values have been initialized with valid data:
// uint8_t * buffer
// unsigned int length
// uint32_t sum
auto result = psyqo::adler32_bytes(buffer, length, sum);Trade-offs and warnings
Pointer/reference arguments are borrowed unless the source contract says otherwise; keep them valid for the complete operation and never assume null is accepted.
