Значение, возвращаемое system, отследить не могу, т.к. проект является демоном.
Ээээ, а посмотреть чему равен код возврата system(а он есть!) через syslog - религия не позволяет?
Цитата из man system:
RETURN VALUE
The return value of system() is one of the following:
* If command is NULL, then a nonzero value if a shell is available, or 0 if no shell is available.
* If a child process could not be created, or its status could not be retrieved, the return value is -1.
* If a shell could not be executed in the child process, then the return value is as though the child shell terminated by calling _exit(2) with
the status 127.
* If all system calls succeed, then the return value is the termination status of the child shell used to execute command. (The termination sta-
tus of a shell is the termination status of the last command it executes.)
In the last two cases, the return value is a "wait status" that can be examined using the macros described in waitpid(2). (i.e., WIFEXITED(), WEX-
ITSTATUS(), and so on).
system() does not affect the wait status of any other children.Для работы с syslog кури man openlog, например
