[求助]急急急急Vxworks目标机与Linux主机间通过FTP实现文件传输的问题

  Vxworks作为客户端,Linux作为服务器!
现在用过两种方法试着文件读写:
1.在tornado2.2中进入SHELL,执行Iam用户名和密码,
iam("jhb","jhb")
value=0=0X0
利用Whoami查看后有用户显示
whoami
jhb
value=4=0x4
然后运行netDevCreate("FTP:","Host",1),执行Devs可以看到有Ftp虚拟设备
netDevCreate("ftp:","host",1)
value=0=0x0
devs
drv name
0/null
1/tyCo/0
2/pcConsole/0
2/pcConsole/1
4/fd0
4/ata0a
6/host:
7/vio
6/ftpdev:
6/ftp:
value=0=0x0
再运行FD=Open("FTP:\Temp",2),结果返回Value=-1.文件不能被新建.

2. 我写了一个程序,源码如下:
#include <sys/types.h>
#include <ioLib.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
int fd1,fd2;
usrAtaConfif(0,0,"c:");
char buffer[10] ={'a','b','c','d','e','f','g','h','i','j'} ;
fd1 = open ("c:/temp.txt", O_CREAT|O_RDWR, 0644);
if(fd1 == ERROR){
printf("create file error and error is:%dn",fd1);
}else{
writefile(buffer,fd1);
close(fd1);
}
fd2 = open ("c:/temp.txt", 0, 0644);
if(fd2 == ERROR){
printf("open file error and error is:%dn",fd2);
}else{
readfile(buffer,fd2);
close(fd2);
}
return 0;
}
writefile(char *buf,int fd)
{
int h;
h = write(fd,buf,10);
if(h == ERROR)
printf("write errorn");
else
printf("write filen");
printf("write h is %dn",h);
return;
}
readfile(char *buf,int fd)
{
int h;
h = read(fd,buf,10);
if(h == ERROR)
printf("read errorn");
else{
printf("read h is %dn",h);
printf("string is %sn",buf);
}
return;
}
下载到目标机运行后提示:    write filenwrite h is 10nopen file error and error is:-1n

望各位大虾指点迷津,都做了十来天了!!!随便告知一种方法即可!不胜感谢!!!
