Module generation
This module contains functions that generate ctypes prototypes for the GDAL routines.
source linkClasses
Functions
▶ def bool_output(func, argtypes, errcheck=None) Generate a ctypes function that returns a boolean value.
▶ def chararray_output(func, argtypes, errcheck=True) For functions that return a c_char_p array.
▶ def double_output(func, argtypes, errcheck=False, strarg=False, cpl=False) Generate a ctypes function that returns a double value.
▶ def geom_output(func, argtypes, offset=None) Generate a function that returns a Geometry either by reference or directly (if the return_geom keyword is set to True).
▶ def int64_output(func, argtypes) Generate a ctypes function that returns a 64-bit integer value.
▶ def int_output(func, argtypes, errcheck=None) Generate a ctypes function that returns an integer value.
▶ def srs_output(func, argtypes) Generate a ctypes prototype for the given function with the given C arguments that returns a pointer to an OGR Spatial Reference System.
▶ def string_output(func, argtypes, offset=-1, str_result=False, decoding=None) Generate a ctypes prototype for the given function with the
given argument types that returns a string from a GDAL pointer.
The `const` flag indicates whether the allocated pointer should
be freed via the GDAL library routine VSIFree -- but only applies
only when `str_result` is True.
Reexports
▶ def void_output(func, argtypes, errcheck=True, cpl=False) For functions that don't only return an error code that needs to be examined.
▶ def voidptr_output(func, argtypes, errcheck=True) For functions that return c_void_p.
