Zhongfu,

    An unsigned char will allows the values from 0 to 255.  The array
size can be as big as you want, just declare it or malloc it with enough
memory.  The statement "unsigned char buffer[100]" will give allow up to
a 10 X 10 (or 2 X 50, etc) image with values from 0 to 255.  You say
that "t only can be used to save single character".  Is the compiler
giving you an error message?  If so, then what is the exact error
message and what is the exact line of code that it is complaining about.
Arrays in C are very closely tied to pointers, and if you're not too
familiar with C, it's easy to get the code wrong.

    Thanks,
    PeterM
