# TE_send_text

Send Text Functions

Sends a null-terminated string to a VT terminal emulator.

    int TE_send_text( const char * text );

## Inputs

text | A null terminated text.

TE_send_text sends text to a terminal emulator in VT emulation mode. Nonprintable characters are specified by hexadecimal codes.

Specify nonprintable characters with escaped hexadecimal codes. For example, pass <Escape> as `\x1b`. To insert a literal backslash, escape it with another backslash: '`\\`'.

If the text contains brackets that delimit a parameter (by default, '{' and }'), the runtime environment checks if the text between the brackets is the name of an existing parameter. If so, the {param_name} sting is replaced by the value of the parameter. If no such parameter exists, the text, including the brackets, is sent exactly as entered.

## Return Values

This function returns 0 if it succeeds, and a negative error code if it fails. It also sets the global variable TE_errno.

## Parameterization

You cannot use standard parameterization for any arguments in this function.

## Example

This example shows the use of TE_send_text to send `help` and `log off` commands that contain control codes:

Copy code

    /* *** The terminal type is VT 100. */
    TE_connect(
        "comm-type = telnet;"
        "host-name = myHost;"
        "terminal-id = ;"
        "set-window-size = true;"
        "security-type = unsecured;"
        "terminal-type = vt100;"
        "terminal-model = vt100;"
        "login-command-file = ;"
        "terminal-setup-file = ;"
        , 60000);
    if (TE_errno != TE_SUCCESS)
        return -1;
    TE_wait_cursor(24, 2, 100, 90);
    /* duration = 688, replay duration = 400, difference = 288 */
    lr_think_time(3);
    TE_type("MyHost<kReturn>");
    /* duration = 2579, replay duration = 800, difference = 1779 */
    lr_think_time(18);
    TE_type("MyPassword<kReturn>");
    /* duration = -62, replay duration = 200, difference = -262 */
    lr_think_time(2);
    /* following escape sequence is mapped to "help" command */
    TE_send_text("\x1bOP");
    /* duration = -16, replay duration = 200, difference = -216 */
    lr_think_time(3);
    /* following escape sequence is mapped to "logout" command */
    TE_send_text("\x1bOR");
