explain_uname_or_die - get information about current kernel and report errors
#include <libexplain/uname.h> void explain_uname_or_die(struct utsname *data); int explain_uname_on_error(struct utsname *data);
The explain_uname_or_die function is used to call the uname(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_uname(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_uname_on_error function is used to call the uname(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_uname(3) function, but still returns to the caller. data The data, exactly as to be passed to the uname(2) system call.
The explain_uname_or_die function only returns on success, see uname(2) for more information. On failure, prints an explanation and exits, it does not return. The explain_uname_on_error function always returns the value return by the wrapped uname(2) system call.
The explain_uname_or_die function is intended to be used in a fashion similar to the following example: explain_uname_or_die(data);
uname(2) get name and information about current kernel explain_uname(3) explain uname(2) errors exit(2) terminate the calling process
