CreateProcess的 [英] CreateProcess

问题描述

有没有办法为

创建的进程设置环境（特别是PATH）？


我当前的应用程序是使用正确的路径创建的我希望

来通过这个新创建过程的路径将是我当前的一个独立的过程。


任何想法都会有所帮助。


如果您也可以通过电子邮件将回复发送到
es **** @ cerner，我将不胜感激。 com 除了在这个新闻组中发布，如果

可能。

：DLL，进程和线程：


BOOL

CreateProcess（

LPCTSTR lpApplicationName

，LPTSTR lpCommandLine

，LPSECURITY_ATTRIBUTES lpProcessAttributes

，LPSECURITY_ATTRIBUTES lpThreadAttributes

，BOOL bInheritHandles

，DWORD dwCreationFlags

，LPVOID lpEnvironment

，LPCTSTR lpCurrentDirectory
，L PSTARTUPINFO lpStartupInfo

，LPPROCESS_INFORMATION lpProcessInformation

）;


其中lpEnvironment：

指向环境的指针阻止新进程。如果此参数为NULL，则

新进程使用调用进程的环境。

环境块由以null结尾的空终止块

字符串。每个字符串的形式如下：


name = value


因为等号用作分隔符，

它不能在环境变量的名称中使用。


环境块可以包含Unicode或ANSI字符。

如果环境块由lpEnvironment指向包含Unicode

字符，请确保dwCreationFlags包含CREATE_UNICODE_ENVIRONMENT。


请注意，ANSI环境块由两个零字节终止：

一个用于最后一个字符串，另外一个用于终止块。

Unicode环境块以四个零字节终止：

最后一个字符串字符串，另外两个终止块。

Is there a way to set the environment (specifically the PATH) for a
created process?

My current application was created using the correct path and I want
to "pass" this path to the newly created process which will be an
independent process of my current one.

Any ideas would be helpful.

I''d appreciate it if you could also email the reply to
es****@cerner.com in addition to posting it in this newsgroup if
possible.

Thanks

from MSDN/Platform SDK: DLLs, Processes, and Threads:

BOOL
CreateProcess(
LPCTSTR lpApplicationName
, LPTSTR lpCommandLine
, LPSECURITY_ATTRIBUTES lpProcessAttributes
, LPSECURITY_ATTRIBUTES lpThreadAttributes
, BOOL bInheritHandles
, DWORD dwCreationFlags
, LPVOID lpEnvironment
, LPCTSTR lpCurrentDirectory
, LPSTARTUPINFO lpStartupInfo
, LPPROCESS_INFORMATION lpProcessInformation
);

where lpEnvironment:
Pointer to an environment block for the new process. If this parameter is NULL,
the new process uses the environment of the calling process.
An environment block consists of a null-terminated block of null-terminated
strings. Each string is in the form:

name=value

Because the equal sign is used as a separator,
it must not be used in the name of an environment variable.

An environment block can contain either Unicode or ANSI characters.
If the environment block pointed to by lpEnvironment contains Unicode
characters, be sure that dwCreationFlags includes CREATE_UNICODE_ENVIRONMENT.

Note that an ANSI environment block is terminated by two zero bytes:
one for the last string, one more to terminate the block.
A Unicode environment block is terminated by four zero bytes:
two for the last string, two more to terminate the block.
