| <STRONG>delch</STRONG>, <STRONG>wdelch</STRONG>, <STRONG>mvdelch</STRONG>, <STRONG>mvwdelch</STRONG> - delete character under |
| the cursor in a <STRONG>curses</STRONG> window |
| |
| |
| </PRE> |
| <H2>SYNOPSIS</H2><PRE> |
| <STRONG>#include</STRONG> <STRONG><curses.h></STRONG> |
| |
| <STRONG>int</STRONG> <STRONG>delch(void);</STRONG> |
| <STRONG>int</STRONG> <STRONG>wdelch(WINDOW</STRONG> <STRONG>*win);</STRONG> |
| <STRONG>int</STRONG> <STRONG>mvdelch(int</STRONG> <STRONG>y,</STRONG> <STRONG>int</STRONG> <STRONG>x);</STRONG> |
| <STRONG>int</STRONG> <STRONG>mvwdelch(WINDOW</STRONG> <STRONG>*win,</STRONG> <STRONG>int</STRONG> <STRONG>y,</STRONG> <STRONG>int</STRONG> <STRONG>x);</STRONG> |
| |
| |
| </PRE> |
| <H2>DESCRIPTION</H2><PRE> |
| These routines delete the character under the cursor; all |
| characters to the right of the cursor on the same line are |
| moved to the left one position and the last character on |
| the line is filled with a blank. The cursor position does |
| not change (after moving to <EM>y</EM>, <EM>x</EM>, if specified). (This |
| does not imply use of the hardware delete character fea- |
| ture.) |
| |
| |
| </PRE> |
| <H2>RETURN VALUE</H2><PRE> |
| All routines return the integer <STRONG>ERR</STRONG> upon failure and an <STRONG>OK</STRONG> |
| (SVr4 specifies only "an integer value other than <STRONG>ERR</STRONG>") |
| upon successful completion. |
| |
| |
| </PRE> |
| <H2>NOTES</H2><PRE> |
| Note that <STRONG>delch</STRONG>, <STRONG>mvdelch</STRONG>, and <STRONG>mvwdelch</STRONG> may be macros. |
| |
| |
| </PRE> |
| <H2>PORTABILITY</H2><PRE> |
| These functions are described in the XSI Curses standard, |
| Issue 4. The standard specifies that they return <STRONG>ERR</STRONG> on |
| failure, but specifies no error conditions. |
