yihui	0:86aa62fedb9b	39	* library in a single self-contained file.
yihui	0:86aa62fedb9b	40	*
yihui	0:86aa62fedb9b	41	* Usage example:
yihui	0:86aa62fedb9b	42	* \code
yihui	0:86aa62fedb9b	43	* // Encode
yihui	0:86aa62fedb9b	44	* char buf[1024];

yihui	0:86aa62fedb9b	48	* w = mp_encode_str(w, "hello world", strlen("hello world"));
yihui	0:86aa62fedb9b	49	* w = mp_encode_bool(w, true);
yihui	0:86aa62fedb9b	50	* w = mp_encode_double(w, 3.1415);
yihui	0:86aa62fedb9b	51	*
yihui	0:86aa62fedb9b	52	* // Validate
yihui	0:86aa62fedb9b	53	* const char *b = buf;
yihui	0:86aa62fedb9b	54	* int r = mp_check(&b, w);
yihui	0:86aa62fedb9b	55	* assert(!r)
yihui	0:86aa62fedb9b	56	* assert(b == w);
yihui	0:86aa62fedb9b	57	*

yihui	0:86aa62fedb9b	72	* // ival is 10;
yihui	0:86aa62fedb9b	73	*
yihui	0:86aa62fedb9b	74	* sval = mp_decode_str(&r, &sval_len);
yihui	0:86aa62fedb9b	75	* // sval is "hello world", sval_len is strlen("hello world")
yihui	0:86aa62fedb9b	76	*
yihui	0:86aa62fedb9b	77	* bval = mp_decode_bool(&r);

yihui	0:86aa62fedb9b	86	* \note Supported compilers.
yihui	0:86aa62fedb9b	87	* The implementation requires a C99+ or C++03+ compatible compiler.
yihui	0:86aa62fedb9b	88	*
yihui	0:86aa62fedb9b	89	* \note Inline functions.
yihui	0:86aa62fedb9b	90	* The implementation is compatible with both C99 and GNU inline functions.
yihui	0:86aa62fedb9b	91	* Please define MP_SOURCE 1 before \#include <msgpuck.h> in a single
yihui	0:86aa62fedb9b	92	* compilation unit. This module will be used to store non-inlined versions of
yihui	0:86aa62fedb9b	93	* functions and global tables.
