Replace complex c-variable in files

I need to replace a bunch of 

 &p_Data->scratchBuffer0_U32[ 0 ]

with 

 scratchBuffer0_U32

in a tons of c files in a directory and its sub-directories.

Also, some developers wrote the [ 0 ] as [0] and [ 0]

This would be work:

find your_directory -name "*.c" | xargs sed -i 's/&\(p_Data->scratchBuffer0_U32\)[^]]*]/\1/g'

With GNU sed for -i for pseudo-inplace editing:

find . -type f -exec sed -i 's/&p_Data->scratchBuffer0_U32\[[[:space:]]*0[[:space:]]*\]/scratchBuffer0_U32/g' {} +

If you are using *nix and you are trying to replace a string in multiple files, check out this answer here which shows you how to do a recursive replacement with find and perl.

As per the difference between the brackets, you'll have to run it for all 4 cases -- [0], [ 0], [0 ], and [ 0 ].
