Hi all! Next code: #include <stdio.h> #include <process.h> #include <stdlib.h> int main() { char const* progName="Test.exe"; int ret=spawnl(P_WAIT, progName, progName, 0); printf("RunProg::run: %s %d %d %d\n", progName, ret, errno, _doserrno); return 0; } after compiling with dm compiler (Digital Mars Compiler Version 8.41n) and using sdl.lib (19.03.2003 11:42 397 312 sdl.lib) by bat file with next contenst: set path=d:\dm\bin dmc -o -4 -ml TstRunPg.cpp del *.obj I get next output: RunProg::run: Test.exe -1 7 0 I can't understand what is my fault. I've tried this program under bc 3.1 and it runs Test.exe. Please help me! Sergiy Yakovyn |

Posted in reply to Sergiy Yakovyn | Use NULL, not 0, to terminate the argument list to spawnl: int ret=spawnl(P_WAIT, progName, progName, NULL); Then it works. NULL is a 4 byte value with the L memory model, whereas 0 is 2 bytes. |

Posted in reply to Walter | int ret=spawnl(P_WAIT, progName, progName, NULL); The example above doesn't work. Work only when I've written as below: spawnl(P_WAIT, mProgName, mProgName, NULL, NULL). It looks like NULL is two bytes value at large model under some circumstance. I am using next files: #include <process.h> #include <stdlib.h> #include <types.h> I think it's because next definition in stdlib.h (I compile C++ file). For C files you are right. #ifdef __cplusplus #define NULL 0 #else #define NULL ((void *)0) #endif "Walter" <newshound@digitalmars.com> ÓÏÏÂÝÉÌ/ÓÏÏÂÝÉÌÁ × ÎÏ×ÏÓÔÑÈ ÓÌÅÄÕÀÝÅÅ: news:d40oac$1eam$1@digitaldaemon.com... > Use NULL, not 0, to terminate the argument list to spawnl: > > int ret=spawnl(P_WAIT, progName, progName, NULL); > > Then it works.
