pass a SCM value to a SCM proc from C

pass a SCM value to a SCM proc from C

[Nic Ferrier]

I have a slightly complicated requirement.

>From C I want to:

1. init guile
2. get a reference to a SCM proc
3. make a SCM object from C
4. call the SCM proc from (2) passing it the SCM object from (3)


I can't immediately see how to do this (though I can see how to do
steps 1. to 3.).

Any suggestions would be greatly appreciated.


Nic

scm_call_1 perhaps (recently added to the manual in the cvs).

It is, of course, scm_applyX where X is 0, 1, 2 etc...

It's in the guile doc.

And if the OP is interested there's also scm_call_X which seems
to just call scm_apply and be a little more convenient. This is
all in libguile/eval.c
