sgs_Parse*** [functions]

SGSBOOL sgs_ParseBool( sgs_Context* C, sgs_StkIdx item, sgs_Bool* out )

SGSBOOL sgs_ParseInt( sgs_Context* C, sgs_StkIdx item, sgs_Int* out )

SGSBOOL sgs_ParseReal( sgs_Context* C, sgs_StkIdx item, sgs_Real* out )

SGSBOOL sgs_ParseString( sgs_Context* C, sgs_StkIdx item, char** out, sgs_SizeVal* size )

SGSBOOL sgs_ParseObjectPtr( sgs_Context* C, sgs_StkIdx item, sgs_ObjInterface* iface, sgs_VarObj** out, int strict )

SGSBOOL sgs_ParsePtr( sgs_Context* C, sgs_StkIdx item, void** out )

Attempts to parse the specified item of the current stack frame, returning whether parsing was successful.

SGSBOOL sgs_ParseStringP( sgs_Context* C, sgs_Variable* var, char** out, sgs_SizeVal* size )

Attempts to parse the specified variable, returning whether parsing was successful.

• The parsing rules:
  • for sgs_ParsePtr, unlike every other parsing function, only null/ptr types are considered valid;
  • for sgs_ParseObjectPtr, only objects with the specified interface iface are valid unless strict = 0, then null is valid too;
  • if item is out of bounds, fail;
  • if item has the type null, func or cfunc, fail;
  • if item is of string type and bool is requested, fail;
  • if item is of string type and int/real is requested, try to convert;
  • everything else succeeds.
