418 | * There are several implementations of termcap which read the text into a |
419 | * fixed-size buffer. Generally they strip the newlines from the text, but may |
420 | * not do it until after the buffer is read. Also, "tc=" resolution may be |
421 | * expanded in the same buffer. This function is useful for measuring the size |
422 | * of the best fixed-buffer implementation; the worst case may be much worse. |
