ini file is just as same as a simple binary file. Reading ini file can be achieve same as we read any binary file.
You can have your own format of storing the data in the ini file.
say for example :

first 10 byte is for application version
second 10 byte is for IMEI no
third for bla bla bla...

and read it according to same format.

For example, you can define the ini format as follows:

BlankLine =newline
Comment=BlankLine|(”;”(~newline)*newline)
KeyString=~(“;”|”[”](~newline)*newline
Key=Comment*KeyString?newline
SectionName =”[”(~newline)*”]”newline
Section=SectionName(Key)*
IniFile=Key*Section*EOF
(Character set Σ=ASCII)

Then you can write the corresponding ini parser !!!
