5 | * linux/byteorder_generic.h | ||
6 | * Generic Byte-reordering support | ||
7 | * | ||
8 | * Francois-Rene Rideau <fare@tunes.org> 19970707 | ||
9 | * gathered all the good ideas from all asm-foo/byteorder.h into one file, | ||
10 | * cleaned them up. | ||
11 | * I hope it is compliant with non-GCC compilers. | ||
12 | * I decided to put __BYTEORDER_HAS_U64__ in byteorder.h, | ||
13 | * because I wasn't sure it would be ok to put it in types.h | ||
14 | * Upgraded it to 2.1.43 | ||
15 | * Francois-Rene Rideau <fare@tunes.org> 19971012 | ||
16 | * Upgraded it to 2.1.57 | ||
17 | * to please Linus T., replaced huge #ifdef's between little/big endian | ||
18 | * by nestedly #include'd files. | ||
19 | * Francois-Rene Rideau <fare@tunes.org> 19971205 | ||
20 | * Made it to 2.1.71; now a facelift: | ||
21 | * Put files under include/linux/byteorder/ | ||
22 | * Split swab from generic support. | ||
23 | * | ||
24 | * TODO: | ||
25 | * = Regular kernel maintainers could also replace all these manual | ||
26 | * byteswap macros that remain, disseminated among drivers, | ||
27 | * after some grep or the sources... | ||
28 | * = Linus might want to rename all these macros and files to fit his taste, | ||
29 | * to fit his personal naming scheme. | ||
30 | * = it seems that a few drivers would also appreciate | ||
31 | * nybble swapping support... | ||
32 | * = every architecture could add their byteswap macro in asm/byteorder.h | ||
33 | * see how some architectures already do (i386, alpha, ppc, etc) | ||
34 | * = cpu_to_beXX and beXX_to_cpu might some day need to be well | ||
35 | * distinguished throughout the kernel. This is not the case currently, | ||
36 | * since little endian, big endian, and pdp endian machines needn't it. | ||
37 | * But this might be the case for, say, a port of Linux to 20/21 bit | ||
38 | * architectures (and F21 Linux addict around?). | ||

41 | /* | ||
42 | * The following macros are to be defined by <asm/byteorder.h>: | ||
43 | * | ||
44 | * Conversion of long and short int between network and host format | ||
45 | * ntohl(__u32 x) | ||
46 | * ntohs(__u16 x) | ||
47 | * htonl(__u32 x) | ||
48 | * htons(__u16 x) | ||
49 | * It seems that some programs (which? where? or perhaps a standard? POSIX?) | ||
50 | * might like the above to be functions, not macros (why?). | ||
51 | * if that's true, then detect them, and take measures. | ||
52 | * Anyway, the measure is: define only ___ntohl as a macro instead, | ||
53 | * and in a separate file, have | ||
54 | * unsigned long inline ntohl(x){return ___ntohl(x);} | ||
55 | * | ||
56 | * The same for constant arguments | ||
57 | * __constant_ntohl(__u32 x) | ||
58 | * __constant_ntohs(__u16 x) | ||
59 | * __constant_htonl(__u32 x) | ||
60 | * __constant_htons(__u16 x) | ||
61 | * | ||
62 | * Conversion of XX-bit integers (16- 32- or 64-) | ||
63 | * between native CPU format and little/big endian format | ||
64 | * 64-bit stuff only defined for proper architectures | ||
65 | * cpu_to_[bl]eXX(__uXX x) | ||
66 | * [bl]eXX_to_cpu(__uXX x) | ||
67 | * | ||
68 | * The same, but takes a pointer to the value to convert | ||
69 | * cpu_to_[bl]eXXp(__uXX x) | ||
70 | * [bl]eXX_to_cpup(__uXX x) | ||
71 | * | ||
72 | * The same, but change in situ | ||
73 | * cpu_to_[bl]eXXs(__uXX x) | ||
74 | * [bl]eXX_to_cpus(__uXX x) | ||
75 | * | ||
76 | * See asm-foo/byteorder.h for examples of how to provide | ||
77 | * architecture-optimized versions | ||
