OPENSSL_INIT_SSL(3)        Library Functions Manual        OPENSSL_INIT_SSL(3)

NAME
     OPENSSL_init_ssl - initialise the crypto and ssl libraries

SYNOPSIS
     #include <openssl/ssl.h>

     int
     OPENSSL_init_ssl(uint64_t options, const void *dummy);

DESCRIPTION
     This function is deprecated.  It is never useful for any application
     program to call it explicitly.  The library automatically calls it
     internally with an options argument of 0 whenever needed.  It is safest
     to assume that any function may do so.

     To enable or disable the standard configuration file, instead use
     OPENSSL_config(3) or OPENSSL_no_config(3), respectively.  To load a non-
     standard configuration file, refer to CONF_modules_load_file(3).

     OPENSSL_init_ssl() calls OPENSSL_init_crypto(3),
     SSL_load_error_strings(3), and SSL_library_init(3).

     The options argument is passed on to OPENSSL_init_crypto(3) and the dummy
     argument is ignored.

     If this function is called more than once, none of the calls except the
     first one have any effect.

RETURN VALUES
     OPENSSL_init_ssl() is intended to return 1 on success or 0 on error.

SEE ALSO
     CONF_modules_load_file(3), OPENSSL_config(3), ssl(3)

HISTORY
     OPENSSL_init_ssl() first appeared in OpenSSL 1.1.0 and has been available
     since OpenBSD 6.3.

BUGS
     OPENSSL_init_ssl() silently ignores even more configuration failures than
     OPENSSL_init_crypto(3).
