Embed SQL in C

Hi,

I am new to SQL and I am only a moderate C-programmer, so I need help to
solve the following problem:

I need a C-program that goes something like this:

1) Check how much devices are in the database and look up the IP and
the Port from them from the database.

2) Connect to the computer using the IP and the Port and send a
certain string to this computer.

[the computer echoes to this certain string with another string that
contains 3 values]

3) The received string should be split and each value should be
written in the right field of the SQL database.

I hope you can help me a little bit.
