#include <assert.h>
#include <oski/common.h>
#include <oski/structhint.h>

Functions
void	oski_InitStructHint (oski_structhint_t *hint)
	Initialize a structural hint record.
void	oski_ResetStructHintDiaglens (oski_structhint_t *hint)
	Clears the diagonal length block list, and resets the count of number of diagonal lengths to 0.
int	oski_AllocStructHintDiaglens (oski_structhint_t *hint, int num_lens)
	Attempt to allocate space for some number of diagonal lengths.
void	oski_ResetStructHintBlocksizes (oski_structhint_t *hint)
	Clears the dense block size list, and resets the count of number of block sizes to 0.
int	oski_AllocStructHintBlocksizes (oski_structhint_t *hint, int num_sizes)
	Attempt to allocate space of 'num_sizes' block sizes.
void	oski_ResetStructHint (oski_structhint_t *hint)
	Reset a structural hint record.

Function Documentation

int oski_AllocStructHintBlocksizes (  oski_structhint_t *  hint, int  num_sizes )

Attempt to allocate space of 'num_sizes' block sizes. Parameters: [in,out]  hint  Hint to set. [in]  num_sizes  Number of block sizes to set. Even if the allocation fails, the block size count is set to 'num_sizes' and the previous block size list is lost (freed). If num_sizes is 0, then no space is allocated. Returns: Returns 1 <==> no errors occurred.

int oski_AllocStructHintDiaglens (  oski_structhint_t *  hint, int  num_lens )

Attempt to allocate space for some number of diagonal lengths. Parameters: [in,out]  hint  Hint to which this routine applies. [in]  num_lens  Number of diagonal lengths for which to allocate space. Even if the allocation fails, the diagonal length size count is set to 'num_lens' and the previous diagonal length list is lost (freed). If num_lens is 0, then no space is allocated. Returns: Returns 1 <==> the lists could be allocated.

void oski_InitStructHint (  oski_structhint_t *  hint  )

Initialize a structural hint record. Parameters: [in,out]  hint  Structural hint record. Postcondition: Initializes the fields of a structural hint record to default values.

void oski_ResetStructHint (  oski_structhint_t *  hint  )

Reset a structural hint record. Parameters: [in,out]  hint  Reinitializes a previously allocated and used structural hint record. This routine reinitializes the fields of 'hint' to their default values, and frees any associated data stored with the 'hint' on call to this routine.
