.. 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 "EVP_PKEY_DIGESTSIGN_SUPPORTS_DIGEST 3ossl" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
EVP_PKEY_digestsign_supports_digest - indicate support for signature digest Header "SYNOPSIS" .Vb 3 #include <openssl/evp.h> int EVP_PKEY_digestsign_supports_digest(EVP_PKEY *pkey, OSSL_LIB_CTX *libctx, const char *name, const char *propq); .Ve Header "DESCRIPTION" The EVP_PKEY_digestsign_supports_digest() function queries whether the message digest name is supported for public key signature operations associated with key pkey. The query is done within an optional library context libctx and with an optional property query propq. Header "RETURN VALUES" The EVP_PKEY_digestsign_supports_digest() function returns 1 if the message digest algorithm identified by name can be used for public key signature operations associated with key pkey and 0 if it cannot be used. It returns a negative value for failure. Header "SEE ALSO" \fBEVP_DigestSignInit_ex\|(3), Header "HISTORY" The EVP_PKEY_digestsign_supports_digest() function was added in OpenSSL 3.0.
