mod if: more prototypes and defines
- prototypes for module (cmd_function) with 3, 4, 5, 6 and
variable number of parameters added. The 3-6 versions just extend the
old version with more char* parameters and are kamailio compatible.
The variable number of parameters function is something new and
experimental. It takes the sip_msg, the number of extra parameters
and an array of action_u_t values (the internal routing engine
parameters representation).
- added a magic value for the parameters numbers, to be used by
variable parameter functions (VAR_PARAM_NO)
- moved/added the NO_SCRIPT macro (parameters number magic value for
functions that should not be called from the script) from tm.
Example for a variable number of parameters function:
static cmd_export_t cmds[]={
{"print", print_f_0, 0, 0, REQUEST_ROUTE}, // overload test
{"print", print_f_1, 1, print_fixup_f_1, REQUEST_ROUTE},
{"print", print_f_2, 2, print_fixup_f_2, REQUEST_ROUTE},
{"print", (cmd_function)print_f_var, VAR_PARAM_NO, 0, REQUEST_ROUTE},
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
{0, 0, 0, 0, 0}
};
...
static int print_f_var(struct sip_msg* msg, int no, action_u_t* vals)
{
int r;
for (r=0; r<no; r++)
printf("%s", vals[r].u.string);
printf("\n");
return 1;
}
You can have fixups too, I omitted them for simplicity.
