Detailed Description

STL-free memory utilities.

Function Documentation

copy_n_optimized()

template<typename T >

void copy_n_optimized ( const T *  src, T *  dst, my_size_t  count  )

inline

Copy elements from a source buffer to a destination buffer.

For POD types, delegates to detail::memcpy for optimal codegen. Falls back to an element-wise loop otherwise.

Template Parameters

T	Element type.

Parameters

src	Pointer to the source buffer.
dst	Pointer to the destination buffer.
count	Number of elements to copy.

Here is the call graph for this function:

fill_n_optimized()

template<typename T >

void fill_n_optimized ( T *  ptr, my_size_t  count, const T &  value  )

inline

Fill a contiguous buffer with a given value.

For POD types initialized to zero, delegates to detail::memset for optimal codegen. Falls back to a scalar loop otherwise.

Template Parameters

T	Element type.

Parameters

ptr	Pointer to the start of the buffer.
count	Number of elements to fill.
value	Value to assign to each element.
