Is possible to build a function C/C++ call dynamically? I.e, i have an array with pointer functions and these functions can have different number of parameters and types. These parameters and their types are stored in a database that i'll get depending on the function name that i want to execute with a function pointer.

More or less i want to build a function thrower with any parameter.

Can i build the function call dynamically?

Any idea?
Hello
you can also implement virtual function in C++.
you give some definition of function in the base class and declare it virtual and then give another defintion with/without the same signature in the child class.
This excludes static binding and the function relevant to the data would be called dynamically at runtime. But it does seem a litttle bloated.
I would have a look at the C++ reflection library . Seems interesting though.
Regards.

PYTHON-CONFIG(1)					      General Commands Manual						  PYTHON-CONFIG(1)

NAME
python-config - output build options for python C/C++ extensions or embedding SYNOPSIS
python-config [ --prefix ] [ --exec-prefix ] [ --includes ] [ --libs ] [ --cflags ] [ --ldflags ] [ --help ] DESCRIPTION
python-config helps compiling and linking programs, which embed the Python interpreter, or extension modules that can be loaded dynamically (at run time) into the interpreter. OPTIONS
--cflags print the C compiler flags. --ldflags print the flags that should be passed to the linker. --includes similar to --cflags but only with -I options (path to python header files). --libs similar to --ldflags but only with -l options (used libraries). --prefix prints the prefix (base directory) under which python can be found. --exec-prefix print the prefix used for executable program directories (such as bin, sbin, etc). --help print the usage message. EXAMPLES
To build the singe-file c program prog against the python library, use gcc $(python-config --cflags --ldflags) progr.cpp -o progr.cpp The same in a makefile: CFLAGS+=$(shell python-config --cflags) LDFLAGS+=$(shell python-config --ldflags) all: progr To build a dynamically loadable python module, use gcc $(python-config --cflags --ldflags) -shared -fPIC progr.cpp -o progr.so SEE ALSO
