.SH DESCRIPTION
|
|
|
|
|
scan_netstring attempts to parse the netstring in the input buffer
|
|
|
|
|
(in,len). If the buffer contains a valid netstring, then (*dest,*slen)
|
|
|
|
|
is set to the start and length of the transported string.
|
|
|
|
|
|
|
|
|
|
Note that this string is not zero terminated. No copy is made.
|
|
|
|
|
scan_netstring points it inside the input buffer.
|
|
|
|
|
.SH "RETURN VALUE"
|
|
|
|
|
scan_netstring returns the number of bytes in the netstring (the outer
|
|
|
|
|
representation, not the transported inner string) if parsing worked, or
|
|
|
|
|
0 if the input buffer did not contain a valid (or full) netstring.
|
|
|
|
|
|
|
|
|
|
.SH EXAMPLE
|
|
|
|
|
The raw memory buffer "foo" would become the netstring "3:foo,"
