| Macros | |
| TCPIP_SMTP_MAX_WRITE_SIZE | the max size of data to be written in a discrete string/array email operation: TCPIP_SMTP_StringPut/TCPIP_SMTP_ArrayPut. Excess characters will be discarded. Note that the higher this value, the greater the size of the underlying TCP socket TX buffer Adjust as needed. Normally should not exceed 512 characters. |
| TCPIP_SMTP_SERVER_REPLY_TIMEOUT | How long to wait before assuming the connection has been dropped (default 8 seconds) |
| TCPIP_SMTP_TASK_TICK_RATE | SMTP task rate, milliseconds The default value is 55 milliseconds. The lower the rate (higher the frequency) the higher the module priority and higher module performance can be obtained The value cannot be lower than the TCPIP_STACK_TICK_RATE. |
| TCPIP_SMTP_WRITE_READY_SPACE | the minimum amount of data to ask from the transport/encryption layer when querying the write space |
| SMTP_CONNECT_ERROR | Connection to SMTP server failed |
| SMTP_RESOLVE_ERROR | DNS lookup for SMTP server failed |
| SMTP_SUCCESS | Message was successfully sent |
| Functions | |
| TCPIP_SMTP_ArrayPut | Writes a series of bytes to the SMTP client. |
| TCPIP_SMTP_Flush | Flushes the SMTP socket and forces all data to be sent. |
| TCPIP_SMTP_IsBusy | Determines if the SMTP client is busy. |
| TCPIP_SMTP_IsPutReady | Determines how much data can be written to the SMTP client. |
| TCPIP_SMTP_Put | Writes a single byte to the SMTP client. |
| TCPIP_SMTP_PutIsDone | Indicates that the on-the-fly message is complete. |
| TCPIP_SMTP_StringPut | Writes a string to the SMTP client. |
| TCPIP_SMTP_UsageBegin | Requests control of the SMTP client module. |
| TCPIP_SMTP_UsageEnd | Releases control of the SMTP client module. |
| TCPIP_SMTP_ClientTask | Standard TCP/IP stack module task function. |
| TCPIP_SMTP_MailSend | Initializes the message sending process. |
| Structures | |
| TCPIP_SMTP_CLIENT_MESSAGE | Configures the SMTP client to send a message. |
| TCPIP_SMTP_CLIENT_MODULE_CONFIG | This is type TCPIP_SMTP_CLIENT_MODULE_CONFIG. |
