<h1>标准库函数 - get_eng_font</h1>
|
||
|
||
|
||
<p>原型:extern void get_eng_font(char ch, char *buf, int mode);</p>
|
||
|
||
<p>用法:#include <system.h></p>
|
||
|
||
<p>功能:取英文字符的点阵</p>
|
||
|
||
<p>说明:把字符ch的点阵信息存放在buf中。</p>
|
||
<pre>
|
||
|
||
buf必须有足够的空间容纳返回的数据。
|
||
mode=0时返回8x16点阵信息,mode=1时返回8x8点阵信息。
|
||
</pre>
|
||
|
||
举例:<pre>
|
||
|
||
// get_eng_font.c
|
||
|

||
{
|
||
char buf[32];
|
||
char *s="Global View",*p;
|
||
int i,j,k; // Loop variable
|
||
int x=0,y=0; // screen location to display HZ
|
||
int r; // current byte
|
||
|
||
clrscr();
|
||
gotoxy(10,10); // Hide Cursor
|
||
|
||
x=y=0;

||
x+=8;
