mbedtls_net_init
void mbedtls_net_init(mbedtls_net_context *ctx)
Initialize a context Just makes the context ready to be used or freed safely.
mbedtls_net_set_nonblock
int mbedtls_net_set_nonblock(mbedtls_net_context *ctx)
Set the socket non-blocking.
mbedtls_net_recv_timeout
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,...
mbedtls_net_recv
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.
ssl.h
