NAME

       dexec.h -

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

SYNOPSIS

       #include <stdarg.h>

   Macros
       #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
           ... The arguments to be passed to the program, followed by a (char *) NULL

       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_listap)
       The same as daemon_exec, but without variadic arguments.

       Since:
           0.11
