| <H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE> |
| |
| </PRE> |
| <H3><a name="h3-baudrate">baudrate</a></H3><PRE> |
| The <STRONG>baudrate</STRONG> routine returns the output speed of the ter- |
| minal. 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 ref- |
| erenced 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 charac- |
| ter 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 charac- |
| ters. 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>ter-</STRONG> |
| <STRONG>mattrs</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 func- |
| tions. 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. |
