To help you create portable applications, QNX Neutrino lets you compile for
specific standards and include QNX- or Neutrino-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 QNX- or Neutrino-specific code
If you need to include QNX- Neutrino-specific code in your application, you can wrap it in an #ifdef to make the program more portable.
