About stdlib.h system()

[Zhongli Xu]

Hi all,

I tried to call another .exe file in my own exe file by using the system()
API.
But the return value of system() is -1 and errno is set to ENOENT. It
indicates that the another exe file is not found.

So I copy the another exe to the fake directory: C:\windoes\system32, since
wine always find the exe file there.
And I also set the environment variable "System" and "Path" in the key
HOST_CURRENT_USER/Environment thru regedit.

But still, wine couldn't find the another exe.

Any help is welcomed.

I use the debug channel. Here is the output:

[root@localhost drive_c]# WINEDEBUG=+process,+exec wine ./System.exe
trace:process:init_current_directory starting in L"C:\" 0x10
trace:process:__wine_kernel_init starting process name=L"C:\System.exe"
argv[0]=L"./System.exe"
trace:process:set_entry_point setting FT_Thunk at 0x602ae084 to 00000000
i: -1
ENOENT

Any idea? Thanks in advance.

Use CreateProcess().

You should never use wine as root.

"root" is only for System-Maintenance.

That must be because you're calling the Unix system() function. If you 
want system() to work in Wine applications you must link with msvcrt and 
call its implementation of system().
