Get the procedure/function information.

0 if successful, 1 otherwise.

This function provides information about a procedure or function. The type can be decoded like for any other identifier of a model. Note that a procedure has no return type (type= XPRM_TYP_NOT). The string of parameter types is a text string describing which parameters are expected by the function, it is its signature. This string is composed with the following characters:

i	an integer
r	a real
s	a text string
b	a Boolean
v	a decision variable (type mpvar)
c	a linear constraint (type linctr)
I	a range set
a	an array (of any kind)
e	a set (of any type)
l	a list (of any type)
|xxx|	external type named ` xxx'. A type code may also be given as ` %???' where ` ???' (3 hexadecimal digits) is the code number
!xxx!	the set named ` xxx'
Andx.t	an array indexed by ` ndx' of the type ` t'. ` ndx' is a string describing the type of each indexing set. ` ndx' may be omitted in which case any array of type ` t' is a valid parameter.
Et	a set of type ` t'
Lt	a list of type ` t'
*	function with variable number of parameters (this character is the last one of the string)

For instance, the procedure:

proc(n:integer,
     tab:array(range, set of real, myset) of string,
     flag:boolean)

has the signature ``iAIr!myset!.sb''.
