Some help from Radomir 'The Sheep' Dopieralski can be found on this rgrd thread:

Read it if you don't understand what the map & light source data structures are all about.
 
 
The API:

Annoyances: although libfov is a c library, for some reason compiling a file that contains #include <fov/fov.h> need to be compiled as a c++ program and not as a c program.
''
For instance:''
A file containing the following:
<pre><nowiki>
#include <fov/fov.h>
 
int
main(){
    return 0;
}
</nowiki></pre>
 
will compile as libfov-test.cpp but if named libfov-test.c (and therefor compiled as a c file), gcc will produce the following error:
<pre><nowiki>
In file included from libfov-test.c:1:
/usr/local/include/fov/fov.h:68: error: syntax error before ‘bool’
/usr/local/include/fov/fov.h:83: error: syntax error before ‘}’ token
/usr/local/include/fov/fov.h:102: error: syntax error before ‘*’ token
/usr/local/include/fov/fov.h:123: error: syntax error before ‘*’ token
/usr/local/include/fov/fov.h:150: error: syntax error before ‘*’ token

/usr/local/include/fov/fov.h:185: error: syntax error before ‘*’ token
/usr/local/include/fov/fov.h:197: error: syntax error before ‘*’ token
/usr/local/include/fov/fov.h:218: error: syntax error before ‘*’ token
make: *** [libfov-test.o] Error 1
</nowiki></pre>
 
I don't know why, but would be glad if someone could find out the reason and propose a solution.
