Function Documentation

int explain_fstatfs_on_error ( int  fildes,

Parameters:
fildesThe fildes, exactly as to be passed to the fstatfs(2) system call.
dataThe data, exactly as to be passed to the fstatfs(2) system call.
Returns:
The value returned by the wrapped fstatfs(2) system call.
Example:
This function is intended to be used in a fashion similar to the following example:
 if (explain_fstatfs_on_error(fildes, data) < 0)
 {
     ...cope with error
     ...no need to print error message
 }
