I'm trying my hand a writing C extensions. I've done this for stuff like Matlab before, and was wondering how you do the usual checking of the arguments that are passed in from Guile.
In the manual, 6.13.13.1 "C Support" has a few functions. libguile/numbers.h has a bunch more ... What I have is an extension function, sort of like the bessel function in the tutorial: https://www.gnu.org/software/guile/manual/html_node/A-Sample-Guile-Extension.html What I would like to do is verify that the first argument is an inexact number, larger than 0. How would I go about that? Perhaps some of it could be: SCM_REALP scm_misc_error Any tips?
