Code:
exec 2>/path/to/stderr.log

scds_timerun

scds_timerun(3HA)					 Sun Cluster HA and Data Services					 scds_timerun(3HA)

NAME

       scds_timerun - execute a given command in a given amount of time

SYNOPSIS

       cc [flags...] -I /usr/cluster/include file -L /usr/cluster/lib  -l  dsdev
       #include <rgm/libdsdev.h>

       scha_err_t scds_timerun(scds_handle_t handle, const char *command,
	   time_t timeout, int signal, int *cmd_exit_code

DESCRIPTION

       The  scds_timerun()  function  executes	a specified command using hatimerun(1M). If the command does not complete within the allotted time
       period,which is specified by the timeout argument, scds_timerun() sends a signal, specified by the signal argument, to kill it.

       The command argument does not support I/O redirection.  However, you can write a script to  perform  redirection  and  then  identify  this
       script in the command argument as the command for scds_timerun() to execute.

PARAMETERS

       The following parameters are supported:

       handle		   The handle returned from scds_initialize(3HA)

       command		   String containing the command to run

       timeout		   Time, in seconds, allotted to run the command

       signal		   Signal  to  kill the command if it is still running when the timeout expires. If signal = -1, then SIGKILL is used. See
			   signal(3HEAD).

       cmd_exit_code	   Return code from execution of the command

RETURN VALUES

       The scds_timerun() function returns the following:

       0		   The function succeeded.

       non-zero 	   The function failed.

ERRORS

       SCHA_ERR_NOERR			   The command executed and cmd_exit_code contains the child program's exit status.

       SCHA_ERR_INTERNAL		   The timeout did not occur, but some other error was detected by scds_timerun() that was  not  an  error
					   detected by the child program. Or hatimerun(1M) caught the signal SIGTERM.

       SCHA_ERR_INVAL			   There was an invalid input argument.

       SCHA_ERR_TIMEOUT 		   The timeout occurred before the command specified by the command argument finished executing.

       See  scha_calls(3HA) for a description of other error codes.
