fmt_netstring - convert a memory buffer into a netstring #include <libowfat/fmt.h> size_t fmt_netstring(char *dest,const char *source, size_t len); fmt_netstring creates a netstring from a raw memory buffer and returns the length. fmt_netstring does not append \\0. If dest equals FMT_LEN (i.e. is zero), fmt_netstring returns the number of bytes it would have written. fmt_netstring returns the number of bytes written (or that would have been written, had the destination pointer not pointed to NULL). If the input buffer is implausibly large, fmt_netstring returns 0 instead. The raw memory buffer "foo" would become the netstring "3:foo," http://cr.yp.to/proto/netstrings.txt scan_netstring(3)
