.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "X509_CHECK_ISSUED 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
X509_check_issued - checks if certificate is issued by another certificate Header "SYNOPSIS" .Vb 1 #include <openssl/x509v3.h> \& int X509_check_issued(X509 *issuer, X509 *subject); .Ve Header "DESCRIPTION" This function checks if certificate subject was issued using \s-1CA\s0 certificate issuer. This function takes into account not only matching of issuer field of subject with subject field of issuer, but also compares authorityKeyIdentifier extension of subject with \fBsubjectKeyIdentifier of issuer if authorityKeyIdentifier present in the subject certificate and checks keyUsage field of \fIissuer. Header "RETURN VALUES" Function return X509_V_OK if certificate subject is issued by \fIissuer or some X509_V_ERR* constant to indicate an error.
