hi,
Hello,
I want to check the status of File handle before
reading/writing to file ? How to do this ?
like following
open(FH_IN_FILE, ">file.txt");
# This statement is executed by some other function
close(FH_IN_FILE);
print FH_IN_FILE "SOME DATA";
here before writing to file, i want to check the
status of FH_IN_FILE..(whether file is opened or
closed )
if ( defined fileno FH_IN_FILE ) {
print FH_IN_FILE "SOME DATA";
}
else {
warn "Error: FH_IN_FILE is closed!\n";
}
