| |
| </PRE><H3><a name="h3-baudrate">baudrate</a></H3><PRE> |
| The <STRONG>baudrate</STRONG> routine returns the output speed of the terminal. The |
| number returned is in bits per second, for example <STRONG>9600</STRONG>, and is an |
| integer. |
| |
| |
| </PRE><H3><a name="h3-erasechar_-erasewchar">erasechar, erasewchar</a></H3><PRE> |
| The <STRONG>erasechar</STRONG> routine returns the user's current erase character. |
| |
| The <STRONG>erasewchar</STRONG> routine stores the current erase character in the |
| location referenced by <EM>ch</EM>. If no erase character has been defined, the |
| routine fails and the location referenced by <EM>ch</EM> is not changed. |
| |
| |
| </PRE><H3><a name="h3-has_is_-has_il">has_is, has_il</a></H3><PRE> |
| The <STRONG>has_ic</STRONG> routine is true if the terminal has insert- and delete- |
| character capabilities. |
| |
| The <STRONG>has_il</STRONG> routine is true if the terminal has insert- and delete-line |
| capabilities, or can simulate them using scrolling regions. This might |
| be used to determine if it would be appropriate to turn on physical |
| scrolling using <STRONG>scrollok</STRONG>. |
| |
| |
| </PRE><H3><a name="h3-killchar_-killwchar">killchar, killwchar</a></H3><PRE> |
| The <STRONG>killchar</STRONG> routine returns the user's current line kill character. |
| |
| The <STRONG>killwchar</STRONG> routine stores the current line-kill character in the |
| location referenced by <EM>ch</EM>. If no line-kill character has been defined, |
| the routine fails and the location referenced by <EM>ch</EM> is not changed. |
| |
| |
| </PRE><H3><a name="h3-longname">longname</a></H3><PRE> |
| The <STRONG>longname</STRONG> routine returns a pointer to a static area containing a |
| verbose description of the current terminal. The maximum length of a |
| verbose description is 128 characters. It is defined only after the |
| call to <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG>. The area is overwritten by each call to |
| <STRONG>newterm</STRONG> and is not restored by <STRONG>set_term</STRONG>, so the value should be saved |
| between calls to <STRONG>newterm</STRONG> if <STRONG>longname</STRONG> is going to be used with multiple |
| terminals. |
| |
| |
| </PRE><H3><a name="h3-termattrs_-term_attrs">termattrs, term_attrs</a></H3><PRE> |
| If a given terminal does not support a video attribute that an |
| application program is trying to use, <STRONG>curses</STRONG> may substitute a different |
| video attribute for it. The <STRONG>termattrs</STRONG> and <STRONG>term_attrs</STRONG> functions return |
| a logical <STRONG>OR</STRONG> of all video attributes supported by the terminal using <EM>A</EM><STRONG>_</STRONG> |
| and <EM>WA</EM><STRONG>_</STRONG> constants respectively. This information is useful when a |
| <STRONG>curses</STRONG> program needs complete control over the appearance of the |
| screen. |
| |
| |
| </PRE><H3><a name="h3-termname">termname</a></H3><PRE> |
| The <STRONG>termname</STRONG> routine returns the terminal name used by <STRONG>setupterm</STRONG>. |
| |
| |
| </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE> |
| <STRONG>longname</STRONG> and <STRONG>termname</STRONG> return <STRONG>NULL</STRONG> on error. |
| |
| Routines that return an integer return <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> (SVr4 |
| only specifies "an integer value other than <STRONG>ERR</STRONG>") upon successful |
| completion. |
| |
| |
| </PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE> |
| Note that <STRONG>termattrs</STRONG> may be a macro. |
| |
| |
| </PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE> |
| The XSI Curses standard, Issue 4 describes these functions. It changes |
| the return type of <STRONG>termattrs</STRONG> to the new type <STRONG>attr_t</STRONG>. Most versions of |
| curses truncate the result returned by <STRONG>termname</STRONG> to 14 characters. |
