Proper use of CommandLineToArgvW?

Question

When parsing the command line arguments of a process whose path contains a space, the path is split up into multiple pieces by CommandLineToArgvW.

There exists a folder on all Windows' C: drives called "Program Files."

The MSDN page mentions nothing about this being a problem. Am I just using the function wrong? How am I supposed to predict what words are part of the path otherwise?

Answer 1

CommandLineToArgvW splits the line on spaces - if you need an argument (or the program name) to contain spaces you need to surround it with quotation marks.

• C:\Program Files - argv[0] = C:\Program, argv[1] = Files
• "C:\Program Files" - argv[0] = C:\Program Files

Note that you can get the file path of your process using GetModuleFileName - you can do this to determine whether the path contains a space, and insert the quotes in the command line if needed before parsing it.
