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:
GInputStreamA
GInputStream.The data is owned by the caller of the function. kind-
Type:
FuCrcKindA
FuCrcKind, typicallyFU_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 aNULLGError*.The argument will be left initialized to NULLby 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.
