This provides the endian conversion functions form endian.h on Windows, Linux, *BSD, Mac OS X, and QNX. You still need to use -std=gnu99 instead of -std=c99 for gcc. The functions might actually be macros. Functions: htobe16, htole16, be16toh, le16toh, htobe32, htole32, be32toh, le32toh, htobe64, htole64, be64toh, le64toh. License: I hereby put …

Bresenham Algorithms in C
Some possible implementations of the Bresenham Algorithms in C.
The Bresenham line algorithm is an algorithm which determines which points in an
n-dimensional raster should be plotted in order to form a close approximation
to a straight line between two given points.
It is commonly used to draw lines on a computer screen, as it uses only integer
addition, subtraction and bit shifting, all of which are very cheap operations
in standard computer architectures.
It is one of the earliest algorithms developed in the field of computer graphics.
A minor extension to the original algorithm also deals with drawing circles.
