Unchecked Conversion is necessary because the data is not a string
representation of an integer, but an integer value returned as
a string.  For instance, if the integer is represented as 32 bits,
the string will be returned as a four byte string. Those four bytes
need to be interpreted as an integer instead of as a string.

Ada provides two approaches for solving this problem.

The first is to use unchecked conversion as described by Mr.
Hoos. The second is to define a string and an integer to occupy
the same address. Simply copy the string from Adasockets into
the overlayed string, then read the value as an integer.

The C code example used by the original poster showed the C
equivalent of viewing a string as an integer. There was no conversion
of values as would occur using the 'value attribute.
