get_mem()

template<typename T >

T openvpn::lzo_asym_impl::get_mem ( const void *  p )

inline

Definition at line 83 of file lzoasym_impl.hpp.

get_u16()

size_t openvpn::lzo_asym_impl::get_u16 ( const unsigned char *  p )

inline

Definition at line 97 of file lzoasym_impl.hpp.

Here is the caller graph for this function:

incremental_copy()

void openvpn::lzo_asym_impl::incremental_copy ( unsigned char *  dest, const unsigned char *  src, ssize_t  len  )

inline

This function emulates copying bytes one by one from src to dest. if src+len and dest+len overlap it repeats the non-overlapping section of src until it copied 'len' bytes

A slow simple version of this method looks like this:

do { *dest++ = *src++; } while (–len);

Parameters

src	Source of the memory
dest	Destination of the memory, must be >= src
len	Number of bytes to copy from src to dest
