我找到以下示例来搜索诸如malloc之类的特定函数名称,但是我想在C源文件的函数声明中找到所有函数名称。因此,在ReturnCode HashCreate(Hash** hash, unsigned int table_size)的情况下,我正在寻找HashCreate和行号。由于我不喜欢Python,而且看起来很复杂,所以我问我该怎么做?

from __future__ import print_function
import sys

sys.path.extend(['.', '..'])

from pycparser import c_parser, c_ast, parse_file

class FuncCallVisitor(c_ast.NodeVisitor):
    def __init__(self, funcname):
        self.funcname = funcname

    def visit_FuncCall(self, node):
        if node.name.name == self.funcname:
            print('%s called at %s' % (self.funcname, node.name.coord))


def show_func_calls(filename, funcname):
    ast = parse_file(filename, use_cpp=True,
                     cpp_path='clang',
                     cpp_args=['-E'])
    v = FuncCallVisitor(funcname)
    v.visit(ast)


if __name__ == "__main__":
    if len(sys.argv) > 2:
        filename = sys.argv[1]
        func = sys.argv[2]
    else:
        filename = 'hash.c'
        func = 'malloc'

    show_func_calls(filename, func)

最佳答案

func_defs示例完全符合您的期望:

# Using pycparser for printing out all the functions defined in a
# C file.
