Description

You do not need to worry about the glibtop * server structure if you don't need - the library exports a glibtop_global_server which you can use everywhere a glibtop * is expected.

Most of the library and all of the sysdeps function also have an alias (which is the function name without the <suffix>_l</suffix>, <suffix>_s</suffix> or <suffix>_r</suffix> suffix) which don't take a glibtop * as argument but uses the glibtop_global_server instead.
