def parse_functions(code):
"""
Parses code and returns a list of functions.
Usage:
For this function to work properly
input code needs to be prepared first,
function prepare_for_parsing(code)
has to be called to pre-process the code first.
Input arguments:
code -- code from which we are parsing functions
Output:
List of functions.
Each function has:
type -- type of function (located from beginnig to ' ')
name -- name of function (located between ' ' and '(')
arguments -- list of arguments (located between '(' and ')'
and separated by comma)
Each argument has:
type -- type of the argument
name -- name of the argument
array -- array lenght of argument (optional)
Example:
>>> code = '''actarray_t* actarray_init(
... file_t *file,
... int nb_actions);
...
... actarray_t* mixed_actarray_init(
... file_t **files,
... int nb_actions);
