.. 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 "OPENSSL_FORK_PREPARE 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
OPENSSL_fork_prepare, OPENSSL_fork_parent, OPENSSL_fork_child \- OpenSSL fork handlers Header "SYNOPSIS" .Vb 1 #include <openssl/crypto.h> \& void OPENSSL_fork_prepare(void); void OPENSSL_fork_parent(void); void OPENSSL_fork_child(void); .Ve Header "DESCRIPTION" OpenSSL has state that should be reset when a process forks. For example, the entropy pool used to generate random numbers (and therefore encryption keys) should not be shared across multiple programs. The OPENSSL_fork_prepare(), OPENSSL_fork_parent(), and OPENSSL_fork_child() functions are used to reset this internal state.

Platforms without fork\|(2) will probably not need to use these functions. Platforms with fork\|(2) but without pthread_atfork\|(3) will probably need to call them manually, as described in the following paragraph. Platforms such as Linux that have both functions will normally not need to call these functions as the OpenSSL library will do so automatically.

\fBOPENSSL_init_crypto\|(3) will register these functions with the appropriate handler, when the \s-1OPENSSL_INIT_ATFORK\s0 flag is used. For other applications, these functions can be called directly. They should be used according to the calling sequence described by the pthread_atfork\|(3) documentation, which is summarized here. OPENSSL_fork_prepare() should be called before a fork() is done. After the fork() returns, the parent process should call OPENSSL_fork_parent() and the child process should call OPENSSL_fork_child().

Header "RETURN VALUES" \fBOPENSSL_fork_prepare(), OPENSSL_fork_parent() and OPENSSL_fork_child() do not return values. Header "SEE ALSO" \fBOPENSSL_init_crypto\|(3) Header "HISTORY" These functions were added in OpenSSL 1.1.1. Header "COPYRIGHT" Copyright 2017-2019 The OpenSSL Project Authors. All Rights Reserved.
