.. default-domain:: C
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:
.. code-block:: c
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
Changes since **v0.7.3**:
* Now mis-alignment of columns are fixed: larger numbers are printed via %g and others are printed via %f. Column withs are calculated before print.
* Now values are colorful ;)
* Some print improvements
* New options with default values:
.. code-block:: c
#define CGLM_PRINT_PRECISION 5
#define CGLM_PRINT_MAX_TO_SHORT 1e5
#define CGLM_PRINT_COLOR "\033[36m"
#define CGLM_PRINT_COLOR_RESET "\033[0m"
* Inline prints are only enabled in DEBUG mode and if **CGLM_DEFINE_PRINTS** is defined.
