4.10. Debug interface
-
SQRESULT sq_getfunctioninfo(HSQUIRRELVM v, SQInteger level, SQFunctionInfo *fi)
- Parameters:
v (HSQUIRRELVM) – the target VM
level (SQInteger) – calls stack level
fi (SQFunctionInfo*) – pointer to the SQFunctionInfo structure that will store the closure informations
- Returns:
a SQRESULT.
- Remarks:
the member ‘funcid’ of the returned SQFunctionInfo structure is a unique identifier of the function; this can be useful to identify a specific piece of squirrel code in an application like for instance a profiler. this method will fail if the closure in the stack is a native C closure.
.eg
typedef struct tagSQFunctionInfo {
SQUserPointer funcid; //unique idetifier for a function (all it's closures will share the same funcid)
const SQChar *name; //function name
const SQChar *source; //function source file name
}SQFunctionInfo;
-
void sq_setdebughook(HSQUIRRELVM v)
- Parameters:
v (HSQUIRRELVM) – the target VM
- Remarks:
In order to receive a ‘per line’ callback, is necessary to compile the scripts with the line informations. Without line informations activated, only the ‘call/return’ callbacks will be invoked.
pops a closure from the stack an sets it as debug hook. When a debug hook is set it overrides any previously set native or non native hooks. if the hook is null the debug hook will be disabled.
-
void sq_setnativedebughook(HSQUIRRELVM v, SQDEBUGHOOK hook)
- Parameters:
v (HSQUIRRELVM) – the target VM
hook (SQDEBUGHOOK) – the native hook function
- Remarks:
In order to receive a ‘per line’ callback, is necessary to compile the scripts with the line informations. Without line informations activated, only the ‘call/return’ callbacks will be invoked.
sets the native debug hook. When a native hook is set it overrides any previously set native or non native hooks. if the hook is NULL the debug hook will be disabled.
-
SQRESULT sq_stackinfos(HSQUIRRELVM v, SQInteger level, SQStackInfos *si)
- Parameters:
v (HSQUIRRELVM) – the target VM
level (SQInteger) – calls stack level
si (SQStackInfos*) – pointer to the SQStackInfos structure that will store the stack informations
- Returns:
a SQRESULT.
retrieve the calls stack informations of a ceratain level in the calls stack.
