<PRE><FONT FACE="Helvetiva,Arial,Sans-serif">
Prepares the input string 'bin' of length 'bin_len' of encoding
'bin_encoding' according to the stringrep profile 'profile_name'.
Returns the prepared and allocated string into 'out'. The 'out_len'
indicates the length of the prepared string. This returns the
<A HREF="silcstringprep-SilcStringprepStatus.html">SilcStringprepStatus</A> which indicates the status of the preparation.
For example, if the input string contains prohibited characters
(according to the used profile) this function will return error.
The 'flags' however can be used to modify the behavior of this
function. Caller must free the returned 'out' string.
The output string will be encoded into the character encoding
defined by the 'out_encoding'. This allows caller to have for
example the input string as locale specific string and output string
as UTF-8 encoded string.
If the 'out' is NULL this function merely performs the preparation
process, but does not return anything. In this case this function
could be used to for example verify that an input string that ought
to have been prepared correctly was done so.
Available profile names:
SILC_IDENTIFIER_PREP Prepares SILC identifier strings
SILC_IDENTIFIER_CH_PREP Prepares SILC channel name strings
SILC_IDENTIFIERC_PREP Casefolds identifier strings
SILC_CASEFOLD_PREP Casefolding and normalizing
