This "decay" strips away size information, leaving GDB unaware that the pointer represents an array. As a result, simply printing the pointer in GDB shows only the address or the first element, not the full …

It is often useful to print out several successive objects of the same type in memory; a section of an array, or an array of dynamically determined size for which only a pointer exists in the program.

Set a limit on how many elements of an array GDB will print. If GDB is printing a large array, it stops printing after it has printed the number of elements set by the set print elements command.

If you have a pointer and you are not sure where it points, try `set print symbol-filename on'. Then you can determine the name and source file location of the variable where it points, using `p/a pointer'. …

Since we selected the “array” display hint, this will automatically reflect preferences for printing arrays (as set by set print array). The printer we’ve built will automatically walk a list of arbitrary length; with …
