.. _sq_getfunctioninfo:
.. c:function:: SQRESULT sq_getfunctioninfo(HSQUIRRELVM v, SQInteger level, SQFunctionInfo * fi)
:param HSQUIRRELVM v: the target VM
:param SQInteger level: calls stack level
:param SQFunctionInfo * fi: 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;
.. _sq_setdebughook:
.. c:function:: void sq_setdebughook(HSQUIRRELVM v)
:param HSQUIRRELVM v: 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.
.. _sq_setnativedebughook:
.. c:function:: void sq_setnativedebughook(HSQUIRRELVM v, SQDEBUGHOOK hook)
:param HSQUIRRELVM v: the target VM
:param SQDEBUGHOOK hook: 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.
.. _sq_stackinfos:
.. c:function:: SQRESULT sq_stackinfos(HSQUIRRELVM v, SQInteger level, SQStackInfos * si)
:param HSQUIRRELVM v: the target VM
:param SQInteger level: calls stack level
:param SQStackInfos * si: 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.
