Functions and Macros by Category

## Detailed Description

This group defines all major function and macro groups.

## Modules
| Application Initialization and Termination
| The functions in this section are used on application startup/shutdown and also to control the behaviour of the main event loop of the GUI programs.
| Atomic Operations
| When using multi-threaded applications, it is often required to access or modify memory which is shared between threads.
| Byte Order
| The endian-ness issues (that is the difference between big-endian and little-endian architectures) are important for the portable programs working with the external binary data (for example, data files or data coming from network) which is usually in some fixed, platform-independent format.
| Debugging macros
| Useful macros and functions for error checking and defensive programming.
| Dialogs
| Below are a number of convenience functions for getting input from the user or displaying messages.
| Environment
| These functions allow access to get or change the values of environment variables in a portable way.
| Events
| Below are a number of functions/macros used with wxWidgets event-handling system.
| Files and Directories
| These functions provide a platform-independent API for common file and directory functionality.
| Graphics Device Interface (GDI)
| The following are functions and macros related to GDI (Graphics Device Interface) access.
| Locale-dependent functions
| Below are a number of functions/macros which accept as last parameter a specific wxXLocale instance.
| Logging
| These functions provide a variety of logging functions.
| Math
| The functions in this section are typically related with math operations and floating point numbers.
| Miscellaneous
| Group of miscellaneous functions and macros.
| Network, User and OS
| The functions in this section are used to retrieve information about the current computer and/or user characteristics.
| Process Control
| The functions in this section are used to launch or terminate the other processes.
| Runtime Type Information (RTTI)
| wxWidgets uses its own RTTI ("run-time type identification") system which predates the current standard C++ RTTI and so is kept for backwards compatibility reasons but also because it allows some things which the standard RTTI doesn't directly support (such as creating a class from its name).
| Strings
| Global string functions and macros.
| Threads
| The functions and macros here mainly exist to make it possible to write code which may be compiled in multi thread build (wxUSE_THREADS = 1) as well as in single thread configuration (wxUSE_THREADS = 0).
| Time
| The functions in this section deal with getting the current time and sleeping for the specified time interval.
| Versioning
| The following constants are defined in wxWidgets:
| Wrappers of CRT functions
| For documentation of these functions please refer to the documentation of the standard CRT functions (see e.g. http://www.cppreference.com/wiki/c/start).
