@deftypefun {int} {gnutls_fips140_push_context} (gnutls_fips140_context_t @var{context})
@var{context}: a @code{gnutls_fips140_context_t}
Associate the FIPS @code{context} to the current thread, diverting the
currently active context. If a cryptographic operation is ongoing
in the current thread, e.g., @code{gnutls_aead_cipher_init()} is called
but @code{gnutls_aead_cipher_deinit()} is not yet called, it returns an
error @code{GNUTLS_E_INVALID_REQUEST} .
The operation state of @code{context} will be reset to
@code{GNUTLS_FIPS140_OP_INITIAL} .
This function is no-op if FIPS140 is not compiled in nor enabled
at run-time.
@strong{Returns:} 0 upon success, a negative error code otherwise
@strong{Since:} 3.7.3
