Function Documentation

void explain_fstatvfs_or_die ( int  fildes,
struct statvfs *  data 
)

fildesThe fildes, exactly as to be passed to the fstatvfs(2) system call.
dataThe data, exactly as to be passed to the fstatvfs(2) system call.
Returns:
This function only returns on success, see fstatvfs(2) for more information. On failure, prints an explanation and exits, it does not return.

This function is intended to be used in a fashion similar to the following example:
 explain_fstatvfs_or_die(fildes, data);
