Implement single function in C to sample a frustum

Our ray tracing library (librt) has a few functions pertaining to creating a pattern of rays and shooting them as a bundle (i.e., all at once). We have examples you can follow like rt_gen_circular_grid() in src/librt/mkbundle.c that are very similar, just not the right pattern.
Our "rtshot" command line utility is a simple single-shot utility that can help you test your implementation and make sure it's working correctly. See the code there for mentions of rt_gen_circular_grid() and rt_shootrays().
Sources may be obtained from our Subversion repository: svn checkout https://svn.code.sourceforge.net/p/brlcad/code/brlcad/trunk brlcad
Implement a function, e.g., rt_gen_frustum(), that will create a rectangle of rays originating from a specified point, direction, divergence angle, and options for controlling the sampling density.
