1) This utility contains functions that may be used for file input operations
|

The utility must be linked with the program code with which
|

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

|
||||
2) Specifications for all the functions
|
||||
are provided in a standardized format below.
|
