Top Forums Programming Creating an array to hold posix thread ids: Only dynamic array works Post 302238712 by kmehta on Sunday 21st of September 2008 05:36:06 PM

I am not sure I understand. But you were right, if the above code is placed in the main() function, it works fine, but if I place it in a separate function and call this function from main(), it gives the garbage output.

But I am still not quite sure why it shouldn't work. As you said, first example works fine becuase dynamically allocated threadids exists beyond this fucntion, but it second example it dies immediately. So, shouldnt I face a problem when I place the code directly in the main() function ?? The threadids could die immediately again before the thread is actually spawned, in which case it picks up a garbage output.

Thanks.

NAME
pcre-config - program to return PCRE configuration SYNOPSIS
pcre-config [--prefix] [--exec-prefix] [--version] [--libs] [--libs-posix] [--cflags] [--cflags-posix] DESCRIPTION
pcre-config returns the configuration of the installed PCRE libraries: the options required to compile a program to use them. OPTIONS
--prefix Writes the directory prefix used in the PCRE installation for architecture independent files (e.g. /usr) to standard output. --exec-prefix Writes the directory prefix used in the PCRE installation for architecture dependent files (normally the same as --prefix) to standard output. --version Writes the version of PCRE installed to standard output. --libs Writes to standard output the command line options required to link with PCRE (e.g. -lpcre). --libs-posix Writes to standard output the command line options required to link with the PCRE POSIX emulation library (e.g. -lpcreposix -lpcre). --cflags Writes to standard output the command line options required to compile files that use PCRE (this often includes some -I options, but is blank on debian systems). --cflags-posix Writes to standard output the command line options required to compile files that use the PCRE POSIX emulation library (this often includes some -I options, but is blank on debian systems). Suppress printing of filenames when searching multiple files. AUTHOR This manual page was written by Mark Baker <mark@mnb.org.uk>, for the Debian GNU/Linux system (but may be used by others).
