7=head1 SYNOPSIS
8
9 #include <openssl/conf.h>
10
11 int CONF_modules_load_file(const char *filename, const char *appname,
12			   unsigned long flags);
13 int CONF_modules_load(const CONF *cnf, const char *appname,
14		      unsigned long flags);
15
16=head1 DESCRIPTION
17
18The function CONF_modules_load_file() configures OpenSSL using file
19B<filename> and application name B<appname>. If B<filename> is NULL
20the standard OpenSSL configuration file is used. If B<appname> is
21NULL the standard OpenSSL application name B<openssl_conf> is used.
22The behaviour can be cutomized using B<flags>.
23
24CONF_modules_load() is idential to CONF_modules_load_file() except it
25read configuration information from B<cnf>. 
26
27=head1 NOTES
28
29The following B<flags> are currently recognized:
30
31B<CONF_MFLAGS_IGNORE_ERRORS> if set errors returned by individual
32configuration modules are ignored. If not set the first module error is
33considered fatal and no further modules are loads.
34
35Normally any modules errors will add error information to the error queue. If
36B<CONF_MFLAGS_SILENT> is set no error information is added.
37
38If B<CONF_MFLAGS_NO_DSO> is set configuration module loading from DSOs is
39disabled.
40
41B<CONF_MFLAGS_IGNORE_MISSING_FILE> if set will make CONF_load_modules_file()
42ignore missing configuration files. Normally a missing configuration file
43return an error.
44
45=head1 RETURN VALUE
46
47These functions return 1 for success and a zero or negative value for
48failure. If module errors are not ignored the return code will reflect the
49return value of the failing module (this will always be zero or negative).
