io (input / output e.g. print)

Header: cglm/io.h

There are some built-in print functions which may save your time, especially for debugging.

All functions accept FILE parameter which makes very flexible. You can even print it to file on disk.

In general you will want to print them to console to see results. You can use stdout and stderr to write results to console. Some programs may occupy stdout but you can still use stderr. Using stderr is suggested.

Example to print mat4 matrix:

mat4 transform;
/* ... */
glm_mat4_print(transform, stderr);

NOTE: print functions use %0.4f precision if you need more (you probably will in some cases), you can change it temporary. cglm may provide precision parameter in the future
