pthread_mutex_t and pthread_rwlock_t I am writing code that utilizes mutexes and rwlocks. I know that I can define a mutex or an rwlock with a default value by providing a value of NULL to the appropriate initialization functions: pthread_mutex_init(mymutex,NULL); pthread_rwlock_init(myrwlock,NULL); However, the documentation that I have found so... 20 Apr 2010 16:02
book Bill Cunningham <nospam(a)nspam.invalid> wrote: I received the book I ordered and was very disappointed. The book said copyright 89 and 90 and had one chapter on TCP/IP. I don't even know if the web was around in '89. The C is a very strange syntax pre-ANSI I would say: main(argc, argv) int argc; ... 20 Apr 2010 16:01
ANN: Seed7 Release 2010-04-18 Hello, I have released a new version of Seed7: seed7_05_20100418.tgz In the Seed7 programming language new statements and operators can be declared easily. Types are first class objects and therefore templates/generics need no special syntax. Object orientation is used when it brings advantages and not in plac... 18 Apr 2010 17:31
fork + exec; what are the possible resource leaks? I'm somewhat new to POSIX. It seems that the only way to create a new process is fork. However, fork inherits all file descriptors. exec closes only the file descriptors marked as "close on exec". I generally spawn a separate process because of the isolation this affords. If a process misbehaves, like if it has a r... 20 Apr 2010 19:40
Kill process tree, again Suppose I'm writing a build system, possibly built upon GNU Make. Developers using this build system can write near arbitrary build commands. I do not know all possible build steps as new build steps may be added in the future, and I do not have source code control over all child, grandchildren, etc, as they will b... 17 Apr 2010 15:12
Memory eating... Hello! I've problem with memory leak. After a long investigation. I'm suspecting, that some threads doesn't release their resources. The program starts thousands of threads, and it is not easy to to find when it happens. Is it possible to analyze program memory (i.e. core file), to find thread ids, which ... 16 Apr 2010 18:26
Using a mutex within the data structure that I want to protect I have some data structures that I want to protect using a mutex for the purpose of making thread safe code. Is it ok, to include the mutex datatype within the data structure that I wish to protect? For example: struct buffertable { struct buffer *addr; int sz; unsigned int currentdefault; unsigned ... 17 Apr 2010 10:45
chroot() and popen() won't get along I'm experiencing a weird behaviour in executing programs in a chroot() environment. This is the situation. I have a path like this: /p + |--> /p/popen |--> /p/exe This is popen.c: #include <stdio.h> #include <stdlib.h> #include <unistd.h> int main ( int argc, char *argv[] ) { FILE... 17 Apr 2010 08:34
TCP/IP stream socket Would someone be able to point me in the right direction ? We are looking at implementing a socket server using TCP/IP socket streams on Solaris 10. One of the requirements is that we need to only send TCP ACK messages once our application has flushed the payload to non-volatile memory. We were looking at usi... 15 Apr 2010 16:59 |
