Function Documentation
intdaemon_exec(constchar*dir,int*ret,constchar*prog,...)
Run the specified executable with the specified arguments in the specified directory and return the
return value of the program in the specified pointer. The calling process is blocked until the child
finishes and all child output (either STDOUT or STDIN) has been written to syslog. Running this function
requires that daemon_signal() has been called with SIGCHLD as argument.
Parametersdir Working directory for the process.
ret A pointer to an integer to write the return value of the program to.
prog The path to the executable
... The arguments to be passed to the program, followed by a (char *) NULL
Returns
Nonzero on failure, zero on success

intdaemon_execv(constchar*dir,int*ret,constchar*prog,va_listap)
The same as daemon_exec, but without variadic arguments.
