# pycparser: _c_ast.cfg
#
# Defines the AST Node classes used in pycparser.
#
# Each entry is a Node sub-class name, listing the attributes
# and child nodes of the class:
#   <name>*     - a child node
#   <name>**    - a sequence of child nodes
#   <name>      - an attribute

# ArrayDecl is a nested declaration of an array with the given type.
# dim: the dimension (for example, constant 42)
# dim_quals: list of dimension qualifiers, to support C99's allowing 'const'
#            and 'static' within the array dimension in function declarations.
