函數名: chdir
功 能: 改變工作目錄
用 法: int chdir(const char *path);
程序例:
#include <stdio.h>
#include <stdlib.h>
#include <dir.h>
char old_dir[MAXDIR];
char new_dir[MAXDIR];
int main(void)
{
if (getcurdir(0, old_dir))
{
perror("getcurdir()");
exit(1);
}
printf("Current directory is: \\%s\n", old_dir);
if (chdir("\\"))
{
perror("chdir()");
exit(1);
}
if (getcurdir(0, new_dir))
{
perror("getcurdir()");
exit(1);
}
printf("Current directory is now: \\%s\n", new_dir);
printf("\nChanging back to orignal directory: \\%s\n", old_dir);
if (chdir(old_dir))
{
perror("chdir()");
exit(1);
}
return 0;
}
函數名: getcurdir
功 能: 取指定驅動器的當前目錄
用 法: int getcurdir(int drive, char *direc);
程序例:
#include <stdio.h>
#include <stdlib.h>
#include <dir.h>
char *current_directory(char *path)
{
strcpy(path, "X:\\"); /* 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;
}
