|

* Name: hex2bin
|
||||
*
|
||||
* Description:
|
||||
* Read the Intel HEX ASCII data provided on the serial IN stream and write
|
||||
* the binary to the seek-able serial OUT stream.
|
||||
*
|
||||
* These streams may be files or, in another usage example, the IN stream
|
||||
* could be a serial port and the OUT stream could be a memory stream. This
|
||||
* would decode and write the serial input to memory.
|
||||
*
|
||||
* Input Parameters:
|
||||
* instream - The incoming stream from which Intel HEX data will be
|
||||
* received.
|
||||
* outstream - The outgoing stream in which binary data will be written.
|
||||
* baseaddr - The base address of the outgoing stream. Seeking in the
|
||||
* output stream will be relative to this address.
|
||||
* endpaddr - The end address (plus 1) of the outgoing stream. This
|
||||
* value is used only for range checking. endpaddr must
|
||||
* be larger than baseaddr. A zero value for endpaddr
|
||||
* disables range checking.
|
||||
* swap - Controls byte ordering. See enum hex2bin_swap_e for
|
||||
* description of the values.
|
||||
*
|
||||
* Returned Value
|
||||
* Zero (OK) is returned on success; a negated errno value is returned on
|
||||
* failure.
