"A long time ago in a galaxy far, far away...." we started NFC subsystem refactoring. Starring: - @gornekich - NFC refactoring project lead, architect, senior developer - @gsurkov - architect, senior developer - @RebornedBrain - senior developer Supporting roles: - @skotopes, @DrZlo13, @hedger - general architecture advisors, code review - @Astrrra, @doomwastaken, @Hellitron, @ImagineVagon333 - quality assurance Special thanks: @bettse, @pcunning, @nxv, @noproto, @AloneLiberty and everyone else who has been helping us all this time and contributing valuable knowledges, ideas and source code.

/**
|
|
* @file simple_array.h
|
|
*
|
|
* @brief This file provides a simple (non-type safe) array for elements with
|
|
* (optional) in-place construction support.
|
|
*
|
|
* No append, remove or take operations are supported.
|
|
* Instead, the user must call simple_array_init() in order to reserve the memory for n elements.
|
|
* In case if init() is specified in the configuration, then the elements are constructed in-place.
|
|
*
|
|
* To clear all elements from the array, call simple_array_reset(), which will also call reset()
|
|
* for each element in case if it was specified in the configuration. This is useful if a custom
|
|
* destructor is required for a particular type. Calling simple_array_free() will also result in a
|
|
* simple_array_reset() call automatically.
|
|
*
