/**
* \file imports.c
* Standard C library function wrappers.
*
* Imports are services which the device driver or window system or
* operating system provides to the core renderer. The core renderer (Mesa)
* will call these functions in order to do memory allocation, simple I/O,
* etc.
*
* Some drivers will want to override/replace this file with something
* specialized, but that'll be rare.
*
* Eventually, I want to move roll the glheader.h file into this.
*
* \todo Functions still needed:
* - scanf
* - qsort
* - rand and RAND_MAX
