close
close — closes an open file.
Arguments
- file
- A file pointer to a previously opened
file. This may be either a file in the file system,
or a string opened for read and
write.
Returns
t if the
file had been open and was closed
successfully, else nil.
Description
This function closes a previously opened file. It is not
strictly necessary, as the file will be closed when the
garbage collector recognizes that there are no references
to the file, but it is extremely good policy. This
function will close a string opened for reading and
writing as well.
Example
Gamma> fp = open("myfile.dat","r");
#<File:"myfile.dat">
Gamma> close(fp);
t
Gamma> fp;
#<Destroyed Instance>
Gamma>
