Function Documentation

vector_get_ext_header()

void * vector_get_ext_header

(

const vector_t *const

vector

)

Provides a location where user can put a header for the derived class.

Function returns a pointer to reserved space after vector's control struct. Space for the header extension has to be preallocated on vector creation, size of this region is specified by vector_t::ext_header_size property in vector_opts_t struct.

Parameters

[in]

vector

Pointer to vector.

Returns

Pointer to vector_t::memory

Definition at line 162 of file vector.c.

vector_ext_header_size()

size_t vector_ext_header_size

(

const vector_t *const

vector

)

Retrieves extended header size.

Returns full hierarchy extension size.

Parameters

[in]

vector

Pointer to vector.

Returns

Total size of extensions in bytes.

Definition at line 170 of file vector.c.

vector_data_offset()

size_t vector_data_offset

(

const vector_t *const

vector

)

Compute offset from vector_t::memory to first element.

Parameters

[in]

vector

Pointer to vector.

Returns

Data offset in bytes
