NAME

       dexec.h -

       Contains a robust API for running sub processes with STDOUT and STDERR
       redirected to syslog.

SYNOPSIS

       #include <stdarg.h>

   Defines
       #define DAEMON_EXEC_AVAILABLE   1
           This variable is defined to 1 iff daemon_exec() is supported.
       #define DAEMON_GCC_SENTINEL
           A macro for making use of GCCs printf compilation warnings.
       #define DAEMON_EXECV_AVAILABLE   1
           This variable is defined to 1 iff daemon_execv() is supported.

   Functions
       int daemon_exec (const char *dir, int *ret, const char *prog,...)
           DAEMON_GCC_SENTINEL
           Run the specified executable with the specified arguments in the
           specified directory and return the return value of the program in
           the specified pointer.
       int daemon_execv (const char *dir, int *ret, const char *prog, va_list
           ap)
           The same as daemon_exec, but without variadic arguments.

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_signal() 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

       Returns:
           Nonzero on failure, zero on success

       Since:
           0.4

       Examples:
           testd.c.

   int daemon_execv (const char * dir, int * ret, const char * prog, va_list
       ap)
       The same as daemon_exec, but without variadic arguments. Since:
           0.11
