Turbo C 2.0、Borland C++库函数及用例(39) /* fill string with form of response: X:\ */ path[0] = 'A' + getdisk();
/* replace X with current drive letter */
getcurdir(0, path+3);
/* fill rest of string with current directory */
return(path);
}int main(void)
{
char curdir[MAXPATH]; current_directory(curdir);
printf("The current directory is %s\n", curdir); return 0;
}
函数名: getcwd
功 能: 取当前工作目录
用 法: char *getcwd(char *buf, int n);
程序例:#include <stdio.h>
#include <dir.h>int main(void)
{ char buffer[MAXPATH]; getcwd(buffer, MAXPATH);
printf("The current directory is: %s\n", buffer);
return 0;
}
函数名: getdate
功 能: 取DOS日期
用 法: void getdate(struct *dateblk);
程序例:#include <dos.h>
#include <stdio.h>int main(void)
{
struct date d; getdate(&d); printf("The current year is: %d\n",
d.da_year);
printf("The current day is: %d\n",
d.da_day);
printf("The current month is: %d\n",
d.da_mon);
return 0;
}
函数名: getdefaultpalette
功 能: 返回调色板定义结构
用 法: struct palettetype *far getdefaultpalette(void);
程序例:#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>int main(void)
{/* request auto detection */
int gdriver = DETECT, gmode, errorcode;
int i;/* structure for returning palette copy */
struct palettetype far *pal=(void *) 0;/* initialize graphics and local variables */
initgraph(&gdriver, &gmode, "");/* read result of initialization */
errorcode = graphresult();/* an error occurred */
if (errorcode != grOk)
{
printf("Graphics error: %s\n",
grapherrormsg(errorcode));
printf("Press any key to halt:");
getch();
/* terminate with an error code */
exit(1);
} setcolor(getmaxcolor());/* return a pointer to the default palette */
pal = getdefaultpalette(); for (i=0; i<16; i++)
{
printf("colors[%d] = %d\n", i,
pal->colors[i]);
getch();
}/* clean up */
getch();
closegraph();
