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

|
|
|
|
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.
