Studio:Scl struct sized

The scl_struct_sized pragma

The scl_struct_sized pragma identifies a particular struct or pointer-to-struct as a sized structure. A sized structure typically has bytes allocated past its type definition.

Syntax

#pragma scl_struct_sized(type-name, max-size)

Parameters	Type	Description
type-name	Type	Name of the type that contains the struct/pointer: structure pointer type function name
max-size	Integer	Specifies the number of bytes for the sized struct.

Examples

Example 1

This example shows the declaration for a simple sized struct.

typedef struct {
    int nSize;
    int nSomeJunk;
    int nMoreJunk;
} SimpleSizedStruct;

extern void f(SimpleSizedStruct s);
#pragma scl_struct_sized(SimpleSizedStruct, nSize);

Example 2

This example shows the declaration for a simple sized struct using a pointer.

typedef struct {
    int nSize;
    int nSomeJunk;
    int nMoreJunk;
} SimpleSizedStruct;

extern void f(SimpleSizedStruct* s);
#pragma scl_struct_sized(f.s, nSize);

Example 2

This example shows the declaration of a sized struct containing a conformant array.

#define SOME_BOUND 0
typedef struct {
    int nSize;
    int nSomeJunk;
    int ary[SOME_BOUND];
} ConformantArraySizedStruct;

extern void f(SimpleSizedStruct* s);
#pragma scl_struct_sized(f.s, nSize);
