Error checking functions for GEOS ctypes prototype functions.

Function	`check_dbl`	Check the status code and returns the double value passed in by reference.
Function	`check_geom`	Error checking on routines that return Geometries.
Function	`check_minus_one`	Error checking on routines that should not return -1.
Function	`check_predicate`	Error checking for unary/binary predicate functions.
Function	`check_sized_string`	Error checking for routines that return explicitly sized strings.
Function	`check_string`	Error checking for routines that return strings.
Function	`last_arg_byref`	Return the last C argument's value by reference.
Variable	`free`	Undocumented

def check_dbl(result, func, cargs): (source) ¶

Check the status code and returns the double value passed in by reference.

def check_geom(result, func, cargs): (source) ¶

Error checking on routines that return Geometries.

def check_minus_one(result, func, cargs): (source) ¶

Error checking on routines that should not return -1.

def check_predicate(result, func, cargs): (source) ¶

Error checking for unary/binary predicate functions.

def check_sized_string(result, func, cargs): (source) ¶

Error checking for routines that return explicitly sized strings. This frees the memory allocated by GEOS at the result pointer.

def check_string(result, func, cargs): (source) ¶

Error checking for routines that return strings. This frees the memory allocated by GEOS at the result pointer.

Return the last C argument's value by reference.
