Handling parameters in Shell Functions
Hi,

Please help me with the below situation where I have to handle the parameters passed to a function in a unique way.

Below is the code, which I am trying to execute. I basically want to pass the parameter to a function, where I am trying to get user input into array(s). I want to name the array(s) based on the parameter. Please help me do it!!

Code:
 
#! /bin/sh
 
#GET_TABLE FUNCTION
get_table()
{
  i=0;
 
  set -A $1_file_array NULL;
  set -A $1_db_array NULL;
  set -A $1_table_array NULL;
 
  echo " Please enter tables that are affected in '<DBName>.<Tablename(s)>' format      :"
 
  while read file
  do
    if [ ${#file} -gt 0 ]; then
      $1_file_array[$i]=$file
      $1_db_array[$i]=${file%.*}
      $1_table_array[$i]=${file#*.}
      i=`expr $i + 1`
    fi
  done
  $1_count=${#$1_file_array[@]}
  return $1_count
}
 
# CALL FUNCTION GET_TABLE WITH 'SRC' AS PARM
get_table src
 
# DISPLAY THE LOADED ARRAY
j=0;
src_count=$?
while [ $j -lt src_count ]
do
# BELOW ARE THE ARRAY NAMES I WISH TO SEE
    echo "File: ${src_file_array[$j]}"
    echo "DB: ${src_db_array[$j]}"
    echo "Table: ${src_table_array[$j]}"
    j=`expr $j + 1`
done

Please let me know for any questions.

Thanks
Bharath

Error Handling Classes(3)                                              Coin                                              Error Handling Classes(3)

NAME

       Error Handling Classes -

   Classes
       class SoDebugError
           The SoDebugError class is the internal debugging message passing mechanism.

       This class basically serves two purposes: "
   class SoError
       The SoError class is the base class for all the error handling classes.

       The default error handler just prints messages on the standard error output channel, but this can be overridden by client applications. "
   class SoMemoryError
       The SoMemoryError class is used to inform of problems with memory allocation.

       Modern operating systems takes care of handling most out of memory conditions for you, but in certain situations it can be wise to do some
       manual checking and intervention. This class is provided as an aid to help out in these situations. "
   class SoReadError
       The SoReadError class is used during model import operations.

       During model file import, this class will be used to output any error or warning messages. "

Detailed Description
       The error classes are static classes that contain a callback pointer for handling errors of the given type. Coin has default handlers for
       displaying all the types, but these can be overridden by applications by setting other callbacks.
