E

Causes the preprocessor to send output to stdout.

Syntax

Linux:

-E

Windows:

/E

Arguments

None

Default

OFF

Preprocessed source files are output to the compiler.

Description

This option causes the preprocessor to send output to stdout. Compilation stops when the files have been preprocessed.

When you specify this option, the compiler's preprocessor expands your source module and writes the result to stdout. The preprocessed source contains #line directives, which the compiler uses to determine the source file and line number.

IDE Equivalent

None

Alternate Options

None

Example

To preprocess two source files and write them to stdout, enter the following command:

Linux

icpx -E prog1.cpp prog2.cpp

Windows

icx /E prog1.cpp prog2.cpp
