To help you create portable applications, the QNX Neutrino RTOS lets you compile for
specific standards and include OS-specific code.
Conforming to standards
The header files supplied with the C library provide the proper declarations for the functions and for the number and types of arguments used with them. Constant values used in conjunction with the functions are also declared. The files can usually be included in any order, although individual function descriptions show the preferred order for specific headers.
Including OS-specific code
If you need to include OS-specific code in your application, you can wrap it in an #ifdef to make the program more portable.
