List all available Functions in C

Question

I want to create Bindings for another programming language, and since there are hundreds of functions I am wondering how I can make things more efficient by automating or so.

That means I want a list of all functions from a Header File with data types and return types like this:

void myfunction1(int)
void myfubction2()
void myfunction3(string, string)
....

I've imported the "glad.h" (header only lib) into my Main.

Unfortunately this library only binds system functions which means I can't extract them from the header file. Now I want to know if there is a C function which I can call in the Main which gives me exactly what I want, a list of all currently imported functions like described.

Is there a way to do so for example with relection or something.

I tried to find out a solution + I tried to give chatgpt a html list from the Docs, to extract the func names, but the list has no Definition () and return type, that means I would have to click hundreds of functions manually Copy them look what types and params they take ... and so on.

If you've got Doxygen generated doumentation URL, you could use script:

mkdir tmp;
cd tmp;
wget -r <Documentation URL Root> -L <Documentation URL Root>;
for F in $(find . -name \*.html); do  cat $F | grep '<tr class="memitem:' | sed -e 's/<tr[^>]*>//g' | sed -e 's/&nbsp;/ /g' | sed -e 's/&#160;/ /g' | sed -e 's/<td[^>]*>//g' | sed -e 's/<a[^>]*>//g' | sed -e 's/<\/tr>//g' | sed -e 's/<\/td>//g' | sed -e 's/<\/a>//g' | sed -e 's/$/;/' | egrep  '\(.*\)' >> library_functions.h; done

You doesn't obtain type definitions by this script, and there would be some garbage
