CONF_modules_load_file(3)

     NAME
           CONF_modules_load_file, CONF_modules_load - OpenSSL configuration functions


     SYNOPSIS
           #include <openssl/conf.h>

           int CONF_modules_load_file(const char *filename, const char *appname,
                                     unsigned long flags);
           int CONF_modules_load(const CONF *cnf, const char *appname,
                                unsigned long flags);


     DESCRIPTION
          The function CONF_modules_load_file() configures OpenSSL
          using file filename and application name appname. If
          filename is NULL the standard OpenSSL configuration file is
          used. If appname is NULL the standard OpenSSL application
          name openssl_conf is used.  The behaviour can be cutomized
          using flags.

          CONF_modules_load() is idential to CONF_modules_load_file()
          except it read configuration information from cnf.

     NOTES
          The following flags are currently recognized:

          CONF_MFLAGS_IGNORE_ERRORS if set errors returned by
          individual configuration modules are ignored. If not set the
          first module error is considered fatal and no further
          modules are loads.

          Normally any modules errors will add error information to
          the error queue. If CONF_MFLAGS_SILENT is set no error
          information is added.

          If CONF_MFLAGS_NO_DSO is set configuration module loading
          from DSOs is disabled.

          CONF_MFLAGS_IGNORE_MISSING_FILE if set will make
          CONF_load_modules_file() ignore missing configuration files.
          Normally a missing configuration file return an error.

     RETURN VALUE
          These functions return 1 for success and a zero or negative
          value for failure. If module errors are not ignored the
          return code will reflect the return value of the failing
          module (this will always be zero or negative).
