11 Description: defines to hide compiler specific function stuff.
12 This header is ment to keep all minor functions
13 like PutChProc() used by RawDoFMT().

17 1.0 17.05.05 : inspired by the SDI_#?.h files made by Jens Langner
18 and Dirk Stöcker I created this file to handle rawdofmt()
19 functions.
23 ** This is PD (Public Domain). This means you can do with it whatever you want
24 ** without any restrictions. I only ask you to tell me improvements, so I may
25 ** fix the main line of this files as well.
27 ** To keep confusion level low: When changing this file, please note it in
28 ** above history list and indicate that the change was not made by myself
29 ** (e.g. add your name or nick name).

41 ** Function macros to handle the creation of functions for different
42 ** Operating System versions.
43 ** Currently AmigaOS and MorphOS is supported.
45 ** Currently the following macros are available:
47 ** PUTCHARPROTO
49 ** When using RawDoFmt() from exec.library you need this function to
50 ** store the output created by the function.
52 ** For more information about RawDoFmt() take a look into the
53 ** relevant descriptions in exec.library autodocs.
55 ** Example:
57 ** struct SPrintfStream
58 ** {
59 ** char *Target;
60 ** ULONG TargetSize;
61 ** };
63 ** PUTCHARPROTO( SPrintf_DoChar, char c, struct SPrintfStream *s )
64 ** {
65 ** *(s->Target++) = c;
66 ** }
68 ** ULONG SPrintf(char *format, char *target, ULONG *args)
69 ** {
70 ** struct SPrintfStream s;
72 ** s.Target = target;
74 ** RawDoFmt( format, args, ENTRY( SPrintf_DoChar), &s);
76 ** return( s.Target - target);
77 ** }
79 ** As you can see usage within RawDoFmt() requires using the ENTRY()
80 ** macro.
