Message-ID: <68C4CF842BD2D411AC1600902740B6DA02CDC5B7@mcoexc02.mlm.maxtor.com> From: "Dykstra, Sean" To: "'djgpp AT delorie DOT com'" Subject: FW: Various spawns Date: Fri, 14 Sep 2001 17:08:03 -0600 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2653.19) Content-Type: text/plain; charset="iso-8859-1" Reply-To: djgpp AT delorie DOT com Sorry, what I had intended to say is that spawnlp and spawnvp give me the same slow response as the system command (I have not tried to figure out a way to get to the command prompt with spawnvp). However, I can indeed send a spawnlp and get to the command prompt very quickly, but spawnlp with parameters is slow. To simply reproduce, boot to a dos system with smartdrive disabled (if it is enabled the "system" command works just fine). Then if you write any program that does a system call: (It can also be DOS commands, batch files, or executables, but here is the simplest form I have found to fail, to make it easy to reproduce). system (""); //This function will give you a dos prompt very quickly, you //can then say dir and you get a very quick response and you can write a program that does: system ("dir"); //This function call will take a really, really, really, really long time. //The system I am using is a 933Mhz machine with an award BIOS, but I am told //by one of our other development teams it will fail on any machine The version of DJGPP is: 2.952 My DPMI host is configured as follows: Paging disabled Auto number of page tables to allocate 512k min app mem before paging 3840 paragraphs to reserve when 640K paging 512 paragraphs internal heap memory for CWSDPMI 128Mb maximum size of swap file Value of run option flags - 1 My config.sys Device=himem.sys device=emm386.exe RAM NOEMS dos=high,umb buffershigh=10 There is nothing in my autoexec.bat Thanks!
