13 // INPUT typemaps.
14 // These remap a C pointer to be an "INPUT" value which is passed by value
15 // instead of reference.
16
17 /*
18 The following methods can be applied to turn a pointer into a simple
19 "input" value. That is, instead of passing a pointer to an object,
20 you would use a real value instead.
21
22 int *INPUT
23 short *INPUT
24 long *INPUT
25 long long *INPUT
26 unsigned int *INPUT
27 unsigned short *INPUT
28 unsigned long *INPUT
29 unsigned long long *INPUT
30 unsigned char *INPUT
31 bool *INPUT
32 float *INPUT
33 double *INPUT
34
35 To use these, suppose you had a C function like this :
36
37 double fadd(double *a, double *b) {
38 return *a+*b;
39 }
40
41 You could wrap it with SWIG as follows :
42
43 %include <typemaps.i>
44 double fadd(double *INPUT, double *INPUT);
45
46 or you can use the %apply directive :
47
48 %include <typemaps.i>
49 %apply double *INPUT { double *a, double *b };
50 double fadd(double *a, double *b);
51
52 */
53
54 // OUTPUT typemaps. These typemaps are used for parameters that
55 // are output only. The output value is appended to the result as
56 // a list element.
57
58 /*
59 The following methods can be applied to turn a pointer into an "output"
60 value. When calling a function, no input value would be given for
61 a parameter, but an output value would be returned. In the case of
62 multiple output values, they are returned in the form of a Tcl tuple.
63
64 int *OUTPUT
65 short *OUTPUT
66 long *OUTPUT
67 long long *OUTPUT
68 unsigned int *OUTPUT
69 unsigned short *OUTPUT
70 unsigned long *OUTPUT
71 unsigned long long *OUTPUT
72 unsigned char *OUTPUT
73 bool *OUTPUT
74 float *OUTPUT
75 double *OUTPUT
76
77 For example, suppose you were trying to wrap the modf() function in the
78 C math library which splits x into integral and fractional parts (and
79 returns the integer part in one of its parameters).K:
80
81 double modf(double x, double *ip);
82
83 You could wrap it with SWIG as follows :
84
85 %include <typemaps.i>
86 double modf(double x, double *OUTPUT);
87
88 or you can use the %apply directive :
89
90 %include <typemaps.i>
91 %apply double *OUTPUT { double *ip };
92 double modf(double x, double *ip);
93
94 The Tcl output of the function would be a tuple containing both
95 output values.
96
97 */
98
99 // INOUT
100 // Mappings for an argument that is both an input and output
101 // parameter
102
103 /*
104 The following methods can be applied to make a function parameter both
105 an input and output value. This combines the behavior of both the
106 "INPUT" and "OUTPUT" methods described earlier. Output values are
107 returned in the form of a Tcl tuple.
108
109 int *INOUT
110 short *INOUT
111 long *INOUT
112 long long *INOUT
113 unsigned int *INOUT
114 unsigned short *INOUT
115 unsigned long *INOUT
116 unsigned long long *INOUT
117 unsigned char *INOUT
118 bool *INOUT
119 float *INOUT
120 double *INOUT
121
122 For example, suppose you were trying to wrap the following function :
123
124 void neg(double *x) {
125 *x = -(*x);
126 }
127
128 You could wrap it with SWIG as follows :
129
130 %include <typemaps.i>
131 void neg(double *INOUT);
132
133 or you can use the %apply directive :
134
135 %include <typemaps.i>
136 %apply double *INOUT { double *x };
137 void neg(double *x);
138
139 Unlike C, this mapping does not directly modify the input value (since
140 this makes no sense in Tcl). Rather, the modified input value shows
141 up as the return value of the function. Thus, to apply this function
142 to a Tcl variable you might do this :
143
144 x = neg(x)
145
146 Note : previous versions of SWIG used the symbol 'BOTH' to mark
147 input/output arguments. This is still supported, but will be slowly
148 phased out in future releases.
