Question

vxworks中如何创建一个文件，有没有例子

Answer 1

用普通的文件open（）函数就可以了.
#include <ioLib.h>

open( )
NAME
open( ) - open a file

SYNOPSIS

int open
(
const char * name, /* name of the file to open */
int flags, /* O_RDONLY, O_WRONLY, O_RDWR, or O_CREAT */
int mode /* mode of file to create (UNIX chmod style) */
)
DESCRIPTION
This routine opens a file for reading, writing, or updating, and returns a file descriptor for that file. The arguments to open( ) are the filename and the type of access:

O_RDONLY (0) (or READ) - open for reading only.
O_WRONLY (1) (or WRITE) - open for writing only.
O_RDWR (2) (or UPDATE) - open for reading and writing.
O_CREAT (0x0200) - create a file.

In general, open( ) can only open pre-existing devices and files. However, for NFS network devices only, files can also be created with open( ) by performing a logical OR operation with O_CREAT and the flags argument. In this case, the file is created with a UNIX chmod-style file mode, as indicated with mode. For example:

fd = open ("/usr/myFile", O_CREAT | O_RDWR, 0644);

Only the NFS driver uses the mode argument.

NOTE
For more information about situations when there are no file descriptors available, see the manual entry for iosInit( ).

RETURNS

A file descriptor number, or ERROR if a file name is not specified, the device does not exist, no file descriptors are available, or the driver returns ERROR.

ERRNO
ELOOP

SEE ALSO
ioLib, creat( )

VARARGS2
其中creat和open效果一样，他们最终调用同一个函数，最终文件保存在你设置里放vxworks的位置，比如我的就放在D:\目录下了，试试看吧

Answer 2

mkdir “文件名”
