Hi All,
We are porting one of our exit to Linux. Exit code uses system() function for some purpose. It works fine on Solaris but on Linux, the return status of system() is always -1 though, the command executed by system() is successfull.
I analysed the code but could not figure out the reason. Later added few statements in sample API code to counter check the behaviour. Its the same. Only, the first application which connects to the queue manager only, for the first time, get return status from system command as 0. All the remaining calls would get -1. Btw, for the sake of testing the command I used was system("ls > /dev/null 2>&1").
Could anyone please, help......
TIA,
Kalpana |

It's normal on *ix to check the errno if a library or system call fails. What is the errno after the -1 return code?
Is -1 perhaps the return code from the program that system() runs via the shell? |

Getting the errno as 10 and strerror(errno)=No child Processes
