Function Documentation
int daemon_exec (const char * dir, int * ret, const char * 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_siginal() has been called with SIGCHLD as argument.
Parameters:
dir 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
Examples: testd.c.
