Function
FwupdPlugincrc_find
since: 2.0.0
Declaration [src]
FuCrcKind
fu_crc_find (
const guint8* buf,
gsize bufsz,
guint32 crc_target
)
Description [src]
Returns the cyclic redundancy kind for the given memory buffer and target CRC.
You can use a very simple buffer to discover most types of standard CRC-32:
guint8 buf[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9 }; g_info(“CRC:%u”, fu_crc_find(buf, sizeof(buf), _custom_crc(buf, sizeof(buf))));.
Available since: 2.0.0
Parameters
buf-
Type:
const guint8*Memory buffer.
The data is owned by the caller of the function. bufsz-
Type:
gsizeSize of
buf. crc_target-
Type:
guint32“correct” CRC value.
Return value
Type: FuCrcKind
A FuCrcKind, or FU_CRC_KIND_UNKNOWN on error.
