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
