There are problems with global shared state and no API stability guarantees, and we can't rely on distros shipping the fixes we need. Both firefox and Chrome bundle their own copies too. Imported from https://github.com/sctplab/usrsctp, commit 547d3b46c64876c0336b9eef297fda58dbe1adaf Date: Thu Jul 23 21:49:32 2020 +0200 Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/issues/870 Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/1465>

/**
|
|
*
|
|
* Routine Description:
|
|
*
|
|
* Computes the CRC32c checksum for the specified buffer using the slicing by 8
|
|
* algorithm over 64 bit quantities.
|
|
*
|
|
* Arguments:
|
|
*
|
|
* p_running_crc - pointer to the initial or final remainder value
|
|
* used in CRC computations. It should be set to
|
|
* non-NULL if the mode argument is equal to CONT or END
|
|
* p_buf - the packet buffer where crc computations are being performed
|
|
* length - the length of p_buf in bytes
|
|
* init_bytes - the number of initial bytes that need to be procesed before
|
|
* aligning p_buf to multiples of 4 bytes
|
|
* mode - can be any of the following: BEGIN, CONT, END, BODY, ALIGN
|
|
*
|
|
* Return value:
|
|
*
|
|
* The computed CRC32c value
