24  * @brief System dependant service routines.
25  * All system-specific function and non-standard C/C++ routines go here
26  *
27  * FPDFAPI PREDEFINED MACROES
28  *
29  * FPDFAPI makes use of a number of predefined macroes to support all kind of platforms
30  * with a single set of codes. In most of times, application developers can ignore those
31  * macroes because they are properly defined according to system or compiler environment
32  * settings. However, sometimes, especially for cross platform development, FPDFAPI might
33  * take incorrect settings of the host platform, rather then the target platform. In such
34  * case, the application developers should manually set necessary macroes in their project
35  * settings.
36  *
37  *
38  * Currently the following macroes are defined:
39  * - #_FX_OS_ The target operating system
40  * - #_FX_COMPILER_ The compiler
41  * - #_FX_CPU_ The CPU
42  * - #_FX_ENDIAN_ Little endian or big endian
43  *
44  * #_FX_OS_ can be one of the followings:
45  * - #_FX_WIN32_DESKTOP_ Windows desktop OS (from Windows 95)
46  * - #_FX_WIN32_MOBILE_ Windows Mobile OS (from Windows CE 4.0)
47  * - #_FX_WIN64_ Windows 64 bit
48  * - #_FX_LINUX_DESKTOP_ Linux Desktop OS
49  * - #_FX_LINUX_EMBEDDED_ Embedded Linux OS
50  * - #_FX_SYMBIAN_ Symbian OS (from 7.0)
51  * - #_FX_MACOSX_ MAC OS X
52  * - #_FX_EMBEDDED_ Embedded OS
53  * - #_FX_SOLARIS_ Solaris 8 or later
54  * - #_FX_PALMOS_ PalmOS (5.0 or later)
55  * - #_FX_NETBSD_ NetBSD
56  * - #_FX_ANDROID_ Android
57  * - #_FX_VXWORKS_ VxWorks
58  *
59  * #_FX_COMPILER_ can be one of the following:
60  * - #_FX_VC6_ Microsoft Visual C++ 6.0
61  * - #_FX_VC7_ Microsoft Visual Studio.Net 2003
62  * - #_FX_VC8_ Microsoft Visual Studio.Net 2005
63  * - #_FX_GCC_ GNU C++ Compiler
64  * - #_FX_ADS_ ADS 1.2 Compiler
65  * - #_FX_RVCT_ RVCT 2.1 Compiler
66  * - #_FX_IARCC_ IAR C/C++ Compiler
67  * - #_FX_NOKIA_X86_ Nokia X86 Compiler
68  * - #_FX_METROWERKS_ Metrowerks C/C++ Compiler (with MSL)
69  * - #_FX_PACC_ Protein C/C++ Compiler (used by PalmOS)
70  * - #_FX_MIPS_SDE_ MIPS SDE
71  *
72  * #_FX_CPU_ can be one of the following:
73  * - #_FX_X86_ 32-bit x86 CPU
74  * - #_FX_X64_ 64-bit x86 CPU
75  * - #_FX_POWERPC_ Power PC
76  * - #_FX_ARM_ ARM
77  * - #_FX_SPARC_ Sparc
78  * - #_FX_MIPS_ MIPS
79  * - #_FX_ARM64_ 64-bit ARM
80  *
81  * #_FX_ENDIAN_ can be one of the following:
82  * - #_FX_BIG_ENDIAN_
83  * - #_FX_LITTLE_ENDIAN_
84  *
85  * #_FX_WORDSIZE_ can be one of the following:
86  * - #_FX_W32_ 32-bit instruct
87  * - #_FX_W64_ 64-bit instruct
