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

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
|
||||||
|
|
