NAME

       gnutls_fips140_set_mode - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       void gnutls_fips140_set_mode(gnutls_fips_mode_t mode, unsigned flags);

ARGUMENTS

       gnutls_fips_mode_t mode
                   the FIPS140-2 mode to switch to

       unsigned flags
                   should be zero or GNUTLS_FIPS140_SET_MODE_THREAD

DESCRIPTION

       That  function  is  not  thread-safe  when changing the mode with no flags (globally), and
       should be called prior to creating any threads. Its behavior with no flags  after  threads
       are created is undefined.

       When  the  flag GNUTLS_FIPS140_SET_MODE_THREAD is specified then this call will change the
       FIPS140-2 mode for this particular thread and not for  the  whole  process.  That  way  an
       application can utilize this function to set and reset mode for specific operations.

       This function never fails but will be a no-op if used when the library is not in FIPS140-2
       mode. When asked to switch to unknown values  for   mode  or  to  GNUTLS_FIPS140_SELFTESTS
       mode, the library switches to GNUTLS_FIPS140_STRICT mode.
