Replacing words inside file

I have a very large code in which I have by mistake I have used unsigned instead of uint64_t. Due to this blunder my code does not work for large values greater than 4 byte. Now I want to recify this mistake...but it impossible for me to go into each file (there are 540 files) and replace unsigned with uint64_t. Is there some linux command or some automated method which may do it for me.

I just want to replace word unsigned by uint64_t. I dont want words like unsignedFunction to get replaced by uint64_t.

EDIT: When I replace it for functions of the following form:

   static inline unsigned readUint32Aligned(const unsigned char* data) { return toHost(*reinterpret_cast<const unsigned*>(data)); }

The converted function being :

   static inline uint64_t readUint32Aligned(const uint64_t char* data) { return toHost(*reinterpret_cast<const uint32_t*>(data)); }

It gives me the error:

error: ‘data’ was not declared in this scope

Is there something other than uint64_t which I can do for replacing, which may work for functions of the above form?

Sorry there isn't its probably a typo.

Use sed and the pattern s/\bunsigned\b/uint64_t/g.

The \b is the interesting bit. In regularl expressions, it matches word boundaries.
