Hello,
just in case you want to check a webserver installation (which is not
explicitly mentioned in Viktor's answer) I want to add this...
In this case (IMHO) the s_client tool of openssl can do what you need. Try
openssl s_client -connect yourhost.example.org:443 -CAfile
SpecialCAFile.

If, by chain, you mean a PEM file with one or more X509 certificates,

Thanks my question was already answered my original certificate was not

Hi Goetz,
Thx again for your help, I finally found what was going wrong with my code.
I was setting a flag to force CRL verification but I did not have a CRL
stored for the CA.
Now everything is running well.
Thx again for your help.
Regards !

It loads all certificate files (and CRL files) in the directory
and generates a short 4 byte hash from the common name of the cert.
No, I didn't even know that function.
What does it do ?

Rather depends on what the OP meant by "verify", and what context
this is to be performed.

Try this:
openssl x509 -in filename.pem -text -noout
You should see an issuer: statement that talks about the CA.

RE: how do i use a CRL file to verify
a certificate against?
ok. You get the CDP from the certificate, load
the CRL from the CDP, verify the CRL against the root cert. to verify that
the signature matches, it has not expired, etc. , then s
through all that, or you can examine some of the samples that
call routines like X509_verify_cert().
