Declaration [src]

GPtrArray*
fu_chunk_array_new (
  const guint8* data,
  gsize data_sz,
  gsize addr_offset,
  gsize page_sz,
  gsize packet_sz,
  GError** error
)

Description [src]

Chunks a linear blob of memory into packets, ensuring each packet does not cross a package boundary and is less that a specific transfer size.

Available since: 2.1.2

Parameters

data

Type: const guint8*

An optional linear blob of memory.

The argument can be NULL.

The data is owned by the caller of the function.

data_sz

Type: gsize

Size of data_sz.

addr_offset

Type: gsize

The hardware address offset, or 0.

page_sz

Type: gsize

The hardware page size, or 0.

packet_sz

Type: gsize

The transfer size, or 0.

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: An array of FuChunk*

Array of packets, or NULL.

The caller of the function takes ownership of the data container, but not the data inside it.
