Pattern Search Special Characters

Although you can enter a pattern exactly as it appears in your source code, you can also use special characters (wildcard characters) to specify a pattern. The following are some of the special characters you can use in Pattern Search Mode in the Browsing Window Pattern text box:

Period (.)	Matches any character.
Asterisk (*)	Matches zero or more occurrences of the preceding character.
Caret (^)	Constrains the search to match the beginning of a line.
Dollar sign ($)	Constrains the search to match the end of a line.
Backslash left angle bracket (\<)	Matches the start of a word.
Backslash right angle bracket (\>)	Matches the end of a word.

Examples of what to type in the Pattern text box:

• To constrain a search to match an entire line, use a caret (^) at the beginning of the query and a dollar sign($) at the end.
• To use a wildcard character as part of a search string and not as a wildcard, precede the wildcard character with a backslash (\).
• To search for all lines that begin with traffic, truck, or any other string beginning with tr:

^tr.*

• To find all the lines that end with the string lanes:

lanes$

• To search for occurrences that begin with get (for example, to find get_foobar, but not widget):

\<get

• To find all occurrences of the word String (for example, to find String *foo, but not XmStringCreate()):

\<String\>

• To search for all occurrences of lanes or lines:

l.nes

• To search for an asterisk that is a literal character and not a wildcard character, (for example, char *window; or foo = *windowID):

*window

Source Browsing Special Characters

Although you can type a name or function exactly as it appears in your source code, you can also use special characters (wildcard characters) to specify a set of character strings. Use the following special characters in Source Browsing Mode in the Browsing Window Match text box:

Period (.)	Matches any character.
Asterisk (*)	Matches zero or more occurrences of the preceding character.

Examples of what to type in the Match text box:

• To search for all occurrences of lanes or lines:

l.nes

• To search for any string that begins with window (for example, window_ui.h or window_popup1_objects):

window.*

A search for window* would also match windo, windon, and so on.
