RGETC rgetc(var string buffer [, integer timeout]) : integer;

Gets a character from the remote machine. Timeout is optional and should be in sec-

onds. If the connection is not initialized, the command is ignored and 0 is returned. If

the connection is initialized, the command waits for a character from the remote. If a

character is received, it is copied into buffer (which is terminated with a null) and 1 is

returned; otherwise 0 is returned. If timeout is specified and no characters are re-

ceived within that period, 0 is returned. If timeout is not specified it waits until a

character is received, or until the connection is dropped.

Example

/* This script illustrates the rgetc command. */

proc main;

string s;

integer timeout;

timeout = 5;

fdisplay("Waiting for a character, timeout is : %d

➥ seconds...", timeout);

if rgetc(s, timeout) then

fdisplay("Character received is : %s^J^M", s);

else

display("No character received^J^M");

endif

endproc

RMDIR rmdir(string path_name) : integer;

Removes the directory from the path specified by path_name. If the directory deletion

is successful, 1 is returned, else 0 is returned.

Example

/* This script illustrates the rmdir command. */

proc main;

string name;

integer len;

len = 45;

display("Example for rmdir command^J^M");

display("Enter directory name to remove : ");

if getstr(name, len) then

if rmdir(name) then

fdisplay("^J^M%s removed^J^M", name);

else

fdisplay("^J^M%s could not be removed^J^M", name);

endif
