Function

FwupdPlugininput_stream_compute_crc32

Declaration [src]

gboolean
fu_input_stream_compute_crc32 (
  GInputStream* stream,
  FuCrcKind kind,
  guint32* crc,
  GError** error
)

Description [src]

Returns the cyclic redundancy check value for the given memory buffer.

NOTE: The initial crc differs from fu_crc32_step() in that it is inverted (to make it symmetrical, and chainable), so for most uses you want to use the value of 0x0, not 0xFFFFFFFF.

Available since:

2.0.0

Parameters

`stream`	`GInputStream`
	A `GInputStream`.
	The data is owned by the caller of the function.
`kind`	`FuCrcKind`
	A `FuCrcKind`, typically `FU_CRC_KIND_B32_STANDARD`.
`crc`	`guint32*`
	Initial and final CRC value.
	The argument will be modified by the function.
`error`	`GError **`
	The return location for a `GError*`, or `NULL`.

Return value

Returns:	`gboolean`
	`TRUE` for success.
