Use this like the C-version. In this Modula-2 version, some of the buffers,
|
||
|
|
that are explicit in the C-version, are hidden. These buffers are initialized
|
||
|
|
by a call to Tgetent. The "ARRAY OF CHAR" parameters must be null-terminated.
|
||
|
|
You can call them with a constant string argument, as these are always
|
||
|
|
null-terminated in our Modula-2 implementation. Also, the strings returned
|
||
|
|
by these routines are null-terminated.
