NAME        top

       gnutls_fips140_set_mode - API function

SYNOPSIS        top

#include <gnutls/gnutls.h>void gnutls_fips140_set_mode(gnutls_fips_mode_tmode, unsignedflags);

ARGUMENTS        top

       gnutls_fips_mode_t mode                   the FIPS140-2 mode to switch to       unsigned flags                   should be zero orGNUTLS_FIPS140_SET_MODE_THREAD

DESCRIPTION        top

       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 flagGNUTLS_FIPS140_SET_MODE_THREADis 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 formode or toGNUTLS_FIPS140_SELFTESTSmode, the library       switches toGNUTLS_FIPS140_STRICTmode.
