For example if i have the piece of code as follows:
CountryName = (char *)malloc((strlen(CountryName)+1)*sizeof(char));
memset(CountryName, 0, strlen(CountryName)+1);
CountryName = SOME VALUE
Now how do i free the memory after use of this code???? :confused: (3 Replies)
Linux Kernels 2.6.16 and up provide a way to instruct the kernel to drop the page cache, inode and dentry caches on command. This tip can help free Linux memory without a reboot.
Note: This is a non-destructive operation. Dirty objects are not freeable, hence; you must run sync beforehand.

Hi guys.
I've a question, if we are using a syscall that receives a string allocated dynamicaly to a determined size, or NUL and it will allocate the apropriate size. We should free the memory or the OS will do it for us?
If a function returns a pointer we should free that poiter when we are done... (7 Replies)

pdebuild-user-mode-linux - pbuilder-user-mode-linux way of doing debuild
SYNOPSIS
pdebuild-user-mode-linux [pdebuild-user-mode-linux options] -- [pbuilder-user-mode-linux options]
DESCRIPTION
A convenience program for pbuilder-user-mode-linux which invokes pbuilder after obtaining appropriate root privilege in a Debian source
directory. One must be inside the source tree containing the debian directory, in order to make it work.
PDEBUILD OPTIONS --buildsourceroot [fakeroot]
The command used to gain root privilege for invoking dpkg-buildpackage
--auto-debsign
Invoke debsign at the end of pdebuild process.
--debsign-k [key-id]
Pass -k option to debsign to specify which keyid to sign.
--buildresult [Directory for build results]
The place which build result is stored.
--configfile [Extra config file to use]
The configuration file is used, but not passed on to pbuilder-user-mode-linux.
--debbuildopts [options to pass to dpkg-buildpackage]
The space-delimited list of options are passed to dpkg-buildpackage. This option appends to pbuilder option --debbuildopts and may
also be used to reset the list of options by passing the empty string.
--use-pdebuild-internal
Uses a different implementation of pdebuild, which calls clean and build inside the chroot, using bind-mounts.
pdebuild-internal tries to run debian/rules clean inside the chroot. To achieve the goal, the working directory is passed on inside
the chroot, in the form of bind-mounting and debuild is run.
This option will not protect the working directory and its parent directories from the build scripts.
-- [pbuilder options]
After the -- symbol, an arbitrary number of pbuilder options can be specified. See pbuilder-user-mode-linux.1 for full list of
options.
There is an exception that --buildresult needs to be specified as pdebuild option before the -- to be effective.
