FwupdPlugin.input_stream_compute_crc32
Description: Reference for FwupdPlugin.input_stream_compute_crc32

### Function

# FwupdPlugininput_stream_compute_crc32

since: 2.0.0

#### 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`

  Type: `GInputStream`

  A `GInputStream`.

  The data is owned by the caller of the function.

`kind`

  Type: `FuCrcKind`

  A `FuCrcKind`, typically `FU_CRC_KIND_B32_STANDARD`.

`crc`

  Type: `guint32*`

  Initial and final CRC value.

  The argument will be modified by the function.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the function if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `gboolean`

`TRUE` for success.
