@deftypefun {void} {gnutls_fips140_set_mode} (gnutls_fips_mode_t @var{mode}, unsigned @var{flags})

@var{mode}: the FIPS140-2 mode to switch to

@var{flags}: should be zero or @code{GNUTLS_FIPS140_SET_MODE_THREAD} 

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 @code{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  @code{mode} or to @code{GNUTLS_FIPS140_SELFTESTS}  mode, the library

switches to @code{GNUTLS_FIPS140_STRICT}  mode.
