Build-time configuration info.
int mbedtls_net_recv(void *ctx, unsigned char *buf, size_t len)
Read at most 'len' characters. If no error occurs, the actual amount read is returned.
int mbedtls_net_accept(mbedtls_net_context *bind_ctx, mbedtls_net_context *client_ctx, void *client_ip, size_t buf_size, size_t *cip_len)
Accept a connection from a remote client.
int mbedtls_net_set_nonblock(mbedtls_net_context *ctx)
Set the socket non-blocking.
int mbedtls_net_send(void *ctx, const unsigned char *buf, size_t len)
Write at most 'len' characters. If no error occurs, the actual amount read is returned.
void mbedtls_net_close(mbedtls_net_context *ctx)
Closes down the connection and free associated data.
struct mbedtls_net_context mbedtls_net_context
int mbedtls_net_recv_timeout(void *ctx, unsigned char *buf, size_t len, uint32_t timeout)
Read at most 'len' characters, blocking for at most 'timeout' seconds. If no error occurs,...
void mbedtls_net_usleep(unsigned long usec)
Portable usleep helper.
void mbedtls_net_free(mbedtls_net_context *ctx)
Gracefully shutdown the connection and free associated data.
int mbedtls_net_bind(mbedtls_net_context *ctx, const char *bind_ip, const char *port, int proto)
Create a receiving socket on bind_ip:port in the chosen protocol. If bind_ip == NULL,...
int mbedtls_net_poll(mbedtls_net_context *ctx, uint32_t rw, uint32_t timeout)
Check and wait for the context to be ready for read/write.
int mbedtls_net_connect(mbedtls_net_context *ctx, const char *host, const char *port, int proto)
Initiate a connection with host:port in the given protocol.
void mbedtls_net_init(mbedtls_net_context *ctx)
Initialize a context Just makes the context ready to be used or freed safely.
int mbedtls_net_set_block(mbedtls_net_context *ctx)
Set the socket blocking.
Macro wrapper for struct's members.
