.. 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 "CRYPTO_MEMCMP 3ossl" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
CRYPTO_memcmp - Constant time memory comparison Header "SYNOPSIS" .Vb 1 #include <openssl/crypto.h> \& int CRYPTO_memcmp(const void *a, const void *b, size_t len); .Ve Header "DESCRIPTION" The CRYPTO_memcmp function compares the len bytes pointed to by a and b for equality. It takes an amount of time dependent on len, but independent of the contents of the memory regions pointed to by a and b. Header "RETURN VALUES" \fBCRYPTO_memcmp() returns 0 if the memory regions are equal and nonzero otherwise. Header "NOTES" Unlike memcmp\|(2), this function cannot be used to order the two memory regions as the return value when they differ is undefined, other than being nonzero.
