The dialog box contains
a list of all the defined functions at the left, and an entry field for
entering the mask filter, that should be a regular expression. For instance for
searching all the functions that begin with 'A' and end with 'z' you just type:
'A.*z'. The 'Search' button will be active when you type something in this
entry field.
By selecting with the mouse (single click) a function, you
will see its prototype at the bottom of the dialog box.
You select a function by double clicking in its name at the
left or if you have selected a number of functions with a regular expression,
by selecting one of them in the list box that appears at the top.
Normally the search will be done only in the files loaded in
the editor. You can include all '.c' files if you select the corresponding
button at the right. The editor will load all the source files of the current
directory, including them in the search for the function definition.
If you click in one of the files that appear in the 'Loaded files' list box, the editor will select all functions that are defined in that file.
