D isabling hover help from a particular library may be preferable, particularly if multiple l i bho ver
libraries overlap in functionality. For example, if a l i bho ver plug-in for a C library were manually
installed, such as the newl i b C library (note that newl i b C library plug-in is not provided in
Red Hat Enterprise Linux 6). The hover help would contain C functions whos names overlap with
those in the GNU C library (provided by default). A user would not want both of these hover helps
active at once, so disabling one would be practical.
When multiple l i bho ver libraries are enabled and there exists a functional overlap between
libraries, the Help content for the function from the first listed library in the H elp b o o ks section will
appear in hover help (that is, in Figure 1.22, “ Enabling/D isabling Hover Help” , g l i bc). For code
completion, l i bho ver will offer all possible alternatives from all enabled l i bho ver libraries.
To use hover help, hover the mouse over a function name or member function name in the C /C + +
Ed it o r. After a short time, no more than a few seconds, l i bho ver will display library documentation
on the selected C function or C++ member function.
