Hi, I'm building a Windows console application in C (my OS is Win2k and I have DevCpp 4.9.6.8). The application is computationally intensive so dominates CPU usage when run. By default, the program compiles to an executable with "Normal" priority and so leads to sluggish performance while running (typically several hours for each data set). I can, of course, manually set the priority to Low via the Win2K Task Manager but a) the setting resets to normal every time I launch another application and b) I'm lazy and would prefer to have the program run in low priority by default. So, I'm wondering if there's a way to compile the program to have "Low" priority from the get-go. I understand this could be purely an OS side-of-the-fence deal but thought I'd ask here in case it can be controlled from within DevCpp. Thanks. Scott |

Thanks for the reply. This is probably naive but I've tried to find "Win32 API" in the DevCpp help and a C Library Reference Guide but to no avail. Is this in a header file? I found a w32api.h file but nothing there about SetPriorityClass.

SetThreadPriority is also a nice function to look at. /Per W On Wed, 13 Nov 2002, Anders Eriksson wrote: > Hello Scott, > > Wednesday, November 13, 2002, 9:46:27 PM, you wrote: > > SW> Thanks for the reply.

Who is the unlucky guy working at TFS Technology - or having an email address there? The mail below bounced back for improper Content Type. Since TFS Technology seems to specialize in secure messaging and Content Filtering, it seems a bit ridiculous that 'nice function to look at' is considered (insert suitable unmentionable word here). Since english isn't my native language - is there anyone else on the list who can find any words in the mail that should trigger content filtering? I didn't even find the word software :-) /Per W On Wed, 13 Nov 2002, Per Westermark wrote: > SetThreadPriority is also a nice function to look at. > > /Per W > > On Wed, 13 Nov 2002, Anders Eriksson wrote: > > > Hello Scott, > > > > Wednesday, November 13, 2002, 9:46:27 PM, you wrote: > > > > SW> Thanks for the reply.

Thanks. Don't I feel silly--didn't think about checking the DevPacks. I've glanced over the list on vUpdate from time to time but none seemed to apply to good ole basic number crunching type programming so I hadn't paid much heed. Forgot that Win API was on the list.
