getch();
return 0;
}

程序例:#include <sys\stat.h>
#include <string.h>
#include <fcntl.h>
#include <io.h>int main(void)
{
int handle;
char buf[11] = "0123456789"; /* change the default file mode from text to binary */
_fmode = O_BINARY; /* create a binary file for reading and writing */
handle = creat("DUMMY.FIL", S_IREAD S_IWRITE); /* write 10 bytes to the file */
write(handle, buf, strlen(buf)); /* close the file */
close(handle);
return 0;
}
函数名: creatnew

#include <io.h>int main(void)
{
int handle; char buf[11] = "0123456789"; /* attempt to create a file that doesn't already exist */
handle = creatnew("DUMMY.FIL", 0); if (handle == -1)
printf("DUMMY.FIL already exists.\n");
else
{
printf("DUMMY.FIL successfully created.\n");
write(handle, buf, strlen(buf));
close(handle);
} return 0;
}
