UTILITY USAGE INSTRUCTIONS:
|
||||
|
||||
1) This utility contains functions that may be used for file input operations
|
||||
using the C programming language with text files.
|
||||
The utility must be linked with the program code with which
|
||||
it will be used.
|
||||
|
||||
2) Specifications for all the functions
|
||||
are provided in a standardized format below.
|
||||
|
||||
3) Use this code at your own risk. There is no guarantee of any performance,
|
||||
implied or otherwise, for any part of this code

The utility must be linked with the program code with which
|
||||
it will be used.
|
||||
|
||||
2) Specifications for all the functions
|
||||
are provided in a standardized format below.
|
||||
|
||||
3) Use this code at your own risk. There is no guarantee of any performance,
|
||||
implied or otherwise, for any part of this code
