Crate term_size [] [src]

System calls for getting the terminal size.

Getting the terminal size is performed using an ioctl command that takes the file handle to the terminal -- which in this case, is stdout -- and populates a structure containing the values.

The size is needed when the user wants the output formatted into columns: the default grid view, or the hybrid grid-details view.

Functions
