** NAME
** eval_input_ss - checks syntax of input for process show_stat
**
** SYNOPSIS
** void eval_input_ss(int argc,
** char *argv[],
** char *status_file_name,
** int *show_day,
** int *show_day_summary,
** int *show_hour,
** int *show_hour_summary,
** int *show_min_range,
** int *show_min,
** int *show_min_summary,
** int *show_year,
** int *arg_counter,
** int *show_time_stamp,
** int *display_format,
** int input,
** int *options)
**
** DESCRIPTION
** This module checks whether the syntax is correct. So far it
** accepts the following parameters:
** -w <work dir> working directory of the AFD
** -f <statistic file> path and name of the statistic file
** -o <file name> Output file name.
** -d [<x>] show all information of day minus x
** -D show total summary on a per day basis
** -h [<x>] show all information of hour minus x
** -H show total summary of last 24 hours
** -mr <x> show last x minutes
** -m [<x>] show all information of minute minus x
** -M [<x>] show total summary of last hour
** -y <x> show all information of year minus x
** -t[u] put in a time stamp for time the output
** is valid. With the u the time is shown
** in unix time.
** -C Output in CSV format.
** -N Show directory name not alias.
** -n Show alias and directory name.
** -R Only show remote dirs.
** -T Numeric total only.
**
** RETURN VALUES
** If any of the above parameters have been specified it returns
** them in the appropriate variable (status_file_name, show_day,
** show_year, arg_counter).
