fitpack_fitters_c Module Reference

C interface to module fitpack_fitters. More...

Data Types
interface	f_associated
	Pointer-identity check. Returns true iff a and b view the same underlying Fortran object (their internal c_ptrs match and are non-null). Useful for C-API consumers that want object identity without exposing raw pointers — e.g. GUI panels checking whether an input view points at the same Fortran allocation as the project that owns it. More...
interface	f_char
	Pointer view of a null-terminated C string: a character(:,c_char), pointer result aliasing the C buffer — no copy, no allocation. Always associated: a null, zero-length or ABSENT input yields a 0-length module sentinel, safe to pass to required character(*) dummies and to trim(). Two overloads: More...
interface	f_pointer
interface	f_poly_pointer
	Per-consumer-module resolver(s) for polymorphic procedure args. One module procedure per abstract base any wrapper in this module consumes — colocated with the consumer so the resolver sees every bound concrete subtype known at THIS module's regen time (cross-package coverage included via the cumulative all_type_parents registry). Local (not exported); consumer wrappers call it via the local generic below. More...

Functions/Subroutines
character(len=:, kind=c_char) function, pointer	from_c_string_ptr_cptr (c_str)
	Pointer view from a type(c_ptr) C string. Aliases the C buffer; always associated (0-length sentinel for null/empty input). The sentinel is a NUL byte viewed as zero-length, so it is simultaneously an empty Fortran string and a valid empty C string: a callee that re-derives the length with strlen (any character(len=1) :: s(*) dummy) stops at the NUL instead of reading on into adjacent statics.
subroutine	c_array_to_string (scalar_len, scalar, ptr)
	Turn array of characters to a character string.
character(len=:, kind=c_char) function, pointer	from_c_string_ptr_arr (c_str)
	Pointer view from a character(*) assumed-size C buffer. The dummy is optional: an absent argument (NULL passed to the optional bind(C) dummy) maps to the 0-length sentinel — always associated, safe for required character(*) callee dummies.
logical(c_bool) function, public	fitpack_fitter_c_is_same (this, that)
	Pointer-identity check: true iff both wrappers point to the same underlying Fortran object (and that object is allocated).
type(c_ptr) function	fitpack_fitter_c_get_pointer (this)
	Get opaque pointer to embedded Fortran object (non-allocating) Abstract types cannot use c_f_pointer; return the raw c_ptr instead.
type(fitpack_curve) function, pointer	fitpack_fitter_c_get_accessor_pointer (this)
	Concrete-typed pointer for reading base-declared components on this proxy-less abstract base. Casts the opaque handle to the first concrete child (fitpack_curve); a base component sits at the same offset in every descendant, so the read is valid for any runtime subtype.
real(c_double) function, public	fitpack_fitter_c_mse (this)
integer(c_int32_t) function, public	fitpack_fitter_c_core_comm_size (this)
subroutine, public	fitpack_fitter_c_destroy_base (this)
subroutine, public	fitpack_fitter_c_core_comm_pack (this, n, buffer)
subroutine, public	fitpack_fitter_c_core_comm_expand (this, n, buffer)
subroutine, public	fitpack_fitter_c_getcomp_c (this, ptr, extents)
	Raw view of component 'c': address of the first element, plus the component's 1 extent(s). Null pointer and zero extents when the object or the component is unallocated; an allocated but zero-sized component still reports its true shape, but has no representable address. Symbol uses the getcomp_ infix (not get_) so it can never collide with a type-bound procedure named get_<component>.
subroutine, public	fitpack_fitter_c_getcomp_wrk (this, ptr, extents)
	Raw view of component 'wrk': address of the first element, plus the component's 1 extent(s). Null pointer and zero extents when the object or the component is unallocated; an allocated but zero-sized component still reports its true shape, but has no representable address. Symbol uses the getcomp_ infix (not get_) so it can never collide with a type-bound procedure named get_<component>.
subroutine, public	fitpack_fitter_c_getcomp_iwrk (this, ptr, extents)
	Raw view of component 'iwrk': address of the first element, plus the component's 1 extent(s). Null pointer and zero extents when the object or the component is unallocated; an allocated but zero-sized component still reports its true shape, but has no representable address. Symbol uses the getcomp_ infix (not get_) so it can never collide with a type-bound procedure named get_<component>.
type(c_ptr) function, public	fitpack_fitter_c_ref_iopt (this)
	Get pointer to scalar property 'iopt'.
type(c_ptr) function, public	fitpack_fitter_c_ref_smoothing (this)
	Get pointer to scalar property 'smoothing'.
type(c_ptr) function, public	fitpack_fitter_c_ref_fp (this)
	Get pointer to scalar property 'fp'.
type(c_ptr) function, public	fitpack_fitter_c_ref_lwrk (this)
	Get pointer to scalar property 'lwrk'.
type(c_ptr) function, public	fitpack_fitter_c_ref_liwrk (this)
	Get pointer to scalar property 'liwrk'.
class(fitpack_fitter) function, pointer	fitpack_fitter_c_get_poly_pointer (this)
