14 | Translate a sequence of arguments into a command line | ||
15 | string, using the same rules as the MS C runtime: | ||
16 | |||
17 | 1) Arguments are delimited by white space, which is either a | ||
18 | space or a tab. | ||
19 | |||
20 | 2) A string surrounded by double quotation marks is | ||
21 | interpreted as a single argument, regardless of white space | ||
22 | contained within. A quoted string can be embedded in an | ||
23 | argument. | ||
24 | |||
25 | 3) A double quotation mark preceded by a backslash is | ||
26 | interpreted as a literal double quotation mark. | ||
27 | |||
28 | 4) Backslashes are interpreted literally, unless they | ||
29 | immediately precede a double quotation mark. | ||
30 | |||
31 | 5) If backslashes immediately precede a double quotation mark, | ||
32 | every pair of backslashes is interpreted as a literal | ||
33 | backslash. If the number of backslashes is odd, the last | ||
34 | backslash escapes the next double quotation mark as | ||
35 | described in rule 3. | ||
