Here is a basic outline of the idea: (Assumes function returns a pointer to a structure populated by get_sql) struct sql_result { int val1; char * val2; ...}; struct sql_result * sql_get ( your arguments); int main (void) { ...
return &a; // Returns a pointer to local struct a} 选项 RETURN_LOCAL:report_fields_and_globals:<boolean> - 如果此选项被设置为 true,该检查器将在本地变量的地址由于被指定给参数的字段或全局变量而超出范围时报告缺陷。默认值为 RETURN_LOCAL:report_fields_and_globals:false。 事件 local_ptr_assign...
that. the struct has a build int operator= which will allow you to easily copy arrays if they are members of a struct. Then you can return the struct by value. Alternatively you could dynamically allocate and return a struct pointer and then have the caller be responsible for its ...

{ int j, k, l; // Struct1 exceeds 64 bits. }; Struct1 func3(int a, double b, int c, float d); // Caller allocates memory for Struct1 returned and passes pointer in RCX, // a in RDX, b in XMM2, c in R9, d pushed on the stack; // callee returns pointer to Struct1...
If the return type is larger than 8 bytes, the Nios II C/C++ compiler treats this program as if a() had passed a pointer to b(). The example below shows how the Nios II C/C++ compiler sees the code in the Returned Struct example above. Returned struct is Larger than 8 Bytes voi...
struct mystruct { int vector[20]; } struct mystruct foo() { struct mystruct bar; ...do something nifty with bar... return bar; } P.S. The C language does not let you return an array unless you either (a) just return a pointer to the type of whatever the array is, and you ...
A pointer to an array points to the first of the array elements and has its type; thus, the return type of the function is a pointer to type char.You need not declare functions with int return type before you call them, although prototypes are recommended so that correct type checking ...

Annotates a parameter that will be changed by the function. It must be valid in both pre-state and post-state, but is assumed to have different values before and after the call. Must apply to a modifiable value. _In_z_ A pointer to a null-terminated string that's used as input. Th...
