NAME

       scan_netstring - parse a netstring

SYNTAX

       #include <libowfat/scan.h>

       size_t scan_netstring(const char *in,size_t len,char** dest, size_t *slen);

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.

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.

EXAMPLE

       The raw memory buffer "foo" would become the netstring "3:foo,"
