Each thread gets it's own copy of the global variable: errno. This is done automatically by the Threads Library. So, have fun!!! Smilie

Basic multithreaded program

I'd like to write a program (I'm flexible on language; C/C++ was my original idea but a scripting language would probably be better) that runs hundreds of programs, but only N = 4 (say) at a time.

Errno.h symbols

Hi, I need to look at a recent copy of /usr/include/errno.h from AIX 7.2 to check some symbols. In particular, I'm curious if it defines EOWNERDEAD and ENOTRECOVERABLE. Can someone who has access to 7.2 please check for me? Thanks! (1 Reply)

curl_global_cleanup(3)						  libcurl Manual					    curl_global_cleanup(3)

NAME
curl_global_cleanup - global libcurl cleanup SYNOPSIS
#include <curl/curl.h> void curl_global_cleanup(void); DESCRIPTION
This function releases resources acquired by curl_global_init(3). You should call curl_global_cleanup(3) once for each call you make to curl_global_init(3), after you are done using libcurl. This function is not thread safe. You must not call it when any other thread in the program (i.e. a thread sharing the same memory) is run- ning. This doesn't just mean no other thread that is using libcurl. Because curl_global_cleanup(3) calls functions of other libraries that are similarly thread unsafe, it could conflict with any other thread that uses these other libraries. See the description in libcurl(3) of global environment requirements for details of how to use this function. SEE ALSO
