.SH DESCRIPTION
|
|
scan_hexdump decodes hexdump data from src into dest.
|
|
It will stop when it encounters any invalid input characters.

It will then write the number of decoded bytes in dest into *destlen,
|
|
and return the number of bytes decoded from src.
|
|
|
|
Note that real world hexdump data is sometimes permitted to
|
|
contain whitespace characters or new lines. This function will not allow
|
|
those and return the decoded data until then.
|
|
|
|
dest can be NULL. destlen can be NULL. dest can be src.
|
|
|
|
.SH "RETURN VALUE"

|
processed from src.
