針對海思平臺system命令佔用資源較大的問題，因此程式中與系統呼叫相關的就只能用函式實現了。

demo

mount.c:

#include <sys/mount.h>

int main(void)
{
    int ret = 0;
    ret = mount("/dev/mmcblk0p1","/mnt/sd_card","vfat",MS_SYNCHRONOUS,"iocharset=utf8");
    if(ret == 0)
	printf("mount success!\n");
    else
	printf("mount failed!\n");
    return 0;
}
 

#include <sys/mount.h>

int main(void)
{
    int ret = 0;
    ret = umount("/mnt/sd_card");
    if(ret == 0)
	printf("umount success!\n");
    else
	printf("umount failed!\n");
    return 0;
}

mksdcard.sh

#!/bin/sh

#建立分割槽，引數為fdisk.param 
fdisk /dev/mmcblk0 < /mnt/victa/fdisk.param 

#格式化分割槽
mkfs.vfat /dev/mmcblk0p1
 

#掛載分割槽
mount -t vfat /dev/mmcblk0p1 /mnt/mmc/
