filehandle

问题 ch = getc(lname); while (ch != EOF) { ch = getc(lname); if (ch == '\n') temp++; //except the line to be deleted if (temp != delete_line) { //copy all lines in file replica.c putc(ch, rep); } } I have a file in which I have the following data Aryan Verma Vinayak Sharma Dev Deol Ameesh Deol the above code basically skips the line of data that I want to by putting the line value in delete_line. Here, temp is initiated to be 1. Now the problem is, this code is skipping the first char, i.e. "A" in

问题 I have 2 input files that I want to modify and create new files if log file doesnt exist .

问题 Here's the relevant excerpt from the documentation of the ref function: The value returned depends on the type of thing the reference is a reference to. Builtin types include: SCALAR ARRAY HASH CODE REF GLOB LVALUE FORMAT IO VSTRING Regexp Based on this, I imagined that calling ref on a filehandle would return 'IO' . Surprisingly, it doesn't: use strict; use warnings; open my $fileHandle, '<', 'aValidFile'; close $fileHandle; print ref $fileHandle; # prints 'GLOB', not 'IO' perlref tries to

问题 I want to add a line to top and bottom of the file. I can do it following way. open (DATA, "</usr/old") || die "cant open old\n"; #file to which line has to be added my @body=<DATA>; close(DATA); open (FILE, ">/usr/new") || die "cant open new\n"; #file after stuff has been added print FILE "9 431"; print FILE "\n"; my $body=@body; for (my $i=0; $i<$body;$i++){ print FILE "$body[$i]";#not using for loop leads to addition of spaces in new file } print FILE "(3,((((1,4),(7,6)),(2,8)),5),9)";

问题 I have a subroutine that takes a filehandle as an argument. How do I make a filehandle from a file path specified on the command line? I don't want to do any processing of this file myself, I just want to pass it off to this other subroutine, which returns an array of hashes with all the parsed data from the file. Here's what the command line input I'm using looks like: $ ./getfile.pl /path/to/some/file.csv Here's what the beginning of the subroutine I'm calling looks like: sub parse { my

问题 I have a class that will let me close process handles in a given process. I have the fundamentals down, and it works flawlessly in Win7 x64, but when I run it in WinXP x86, it hangs and I can't understand why. I feel like I am missing something fairly obvious, here. public static List<handleFinder.SYSTEM_HANDLE_INFORMATION> GetHandles(Process process = null, string IN_strObjectTypeName = null, string IN_strObjectName = null) { int nLength = 0; int nHandleInfoSize = 0x10000; IntPtr ipHandle =

问题 I already know how to get the input from user keyboard. I can use the readLine() method or let input = FileHandle.standardInput let inputData = input.availableData var text = String(data: inputData, encoding: .utf8) But the two methods get also when the user press an arrow key button. I would like to filter the input in order to remove these data. I want that the user can write something, maybe go back with the left arrow key, change something and insert the data without problem.
