### Parameters

*command*<br/>
*command*\
Command to be executed.

*mode*<br/>
*mode*\
Mode of the returned stream.

## Return Value
## Return value

Returns a stream associated with one end of the created pipe. The other end of the pipe is associated with the spawned command's standard input or standard output. The functions return **NULL** on an error. If the error is an invalid parameter, such as if *command* or *mode* is a null pointer, or *mode* is not a valid mode, **errno** is set to **EINVAL**. See the Remarks section for valid modes.

The functions return **NULL** on an error. If the error is caused by an invalid parameter, **errno** is set to **EINVAL**. See the Remarks section for valid modes.

For information about these and other error codes, see [_doserrno, errno, _sys_errlist, and _sys_nerr](../../c-runtime-library/errno-doserrno-sys-errlist-and-sys-nerr.md).

## Remarks

The **_popen** function creates a pipe and asynchronously executes a spawned copy of the command processor with the specified string *command*. The character string *mode* specifies the type of access requested, as follows.
