sg_get_host_info(3) sg_get_host_info(3)

sg_get_host_info, sg_get_host_info_r, sg_free_host_info - get general operating system statistics

#include <statgrab.h>


sg_host_info *sg_get_host_info
(size_t *entries);


sg_host_info *sg_get_host_info_r
(size_t *entries);


sg_error sg_free_host_info
(sg_host_info *data);

These calls return details on the operating system and the machine it's running on.

API Shortcut

function returns data owner
sg_get_host_info sg_host_info * libstatgrab (thread local)
sg_get_host_info_r sg_host_info * caller

The sg_host_info buffer received from sg_get_host_info_r() must be freed using sg_free_host_info() when not needed any more. The caller is responsible for doing it.

The structure returned is of type sg_host_info.
