Function Documentation

◆ fr_type_array_alloc()

void** fr_type_array_alloc	(	TALLOC_CTX *	ctx,
		fr_type_t	type,
		size_t	count
	)

Allocate an array of a given type.

Parameters

[in]	ctx	to allocate array in.
[in]	type	array to allocate.
[in]	count	The number of elements to allocate.

Returns

NULL on error.
A new talloc array.

◆ fr_type_cast()

bool fr_type_cast	(	fr_type_t	dst,
		fr_type_t	src
	)

Return if we're allowed to cast the types.

Parameters

dst	the destination type we wish to cast to
src	the source type we wish to cast to

Definition at line 283 of file types.c.

Here is the caller graph for this function:

◆ fr_type_promote()

fr_type_t fr_type_promote	(	fr_type_t	a,
		fr_type_t	b
	)

Return the promoted type.

We presume that the two types are compatible, as checked by calling fr_type_cast(). The main difference here is that the two types don't have any src / dst relationship. Instead, we just pick one which best suits any value-box comparisons

Note that this function can return a type which is not a or b.

Parameters

a	type one
b	type two

Returns: the promoted type
