mouse_init(3) Svgalib User Manual mouse_init(3)

mouse_init, mouse_init_return_fd - specifically initialize a mouse

#include <vgamouse.h>
int mouse_init(char *dev, int type, int samplerate);
int mouse_init_return_fd(char *dev, int type, int samplerate);

These routines can be used to open the mouse manually, ignoring the mouse types or devices specified in the config file.
dev is the name of the mouse device (defaults to /dev_mouse).
samplerate may be one MOUSE_DEFAULTSAMPLERATE(150) or any other value. Probably it is in Hz.
type is one of the types which are listed already in vga_getmousetype(3).
If these routines are used it is not necessary to call vga_setmousesupport(3), but it's probably better to not use these and use vga_setmousesupport(3) instead.
The return_fd version returns the file descriptor of the mouse device to allow you to do further tricks with the mouse (but the filehandle may change during a VC switch). The other version just returns 0 if successful. Both return -1 on error.

This manual page was edited by Michael Weller <>. The exact source of the referenced function as well as of the original documentation is unknown.
It is very likely that both are at least to some extent are due to Harm Hanemaayer <>.
Occasionally this might be wrong. I hereby asked to be excused by the original author and will happily accept any additions or corrections to this first version of the svgalib manual.
