typedef struct eformat::write::node_t eformat::write::node_t |
Defines what is a valid "I/O vector" (a.k.a. iov) node list for eformat
void eformat::write::cat | ( | node_t * | n, |
const struct iovec * | v, | ||
uint32_t | count | ||
) |
Concatenates a set of IOV's to make up a list as required by some eformat::write functionality.
n | the first node_t of a vector of node_t's. The C array pointed by n should have at least "count" available positions |
v | the first IOV node of a vector |
count | the number of IOV nodes pointed by "v" |

void eformat::write::cat | ( | node_t * | n, |
uint32_t | count | ||
) |
Concatenates an already set vector of eformat::write::node_t to make up a valid list.
uint32_t eformat::write::copy | ( | const node_t & | list, |
uint32_t * | dest, | ||
size_t | max | ||
) |
Performs a memcpy like operation, concatenating the list given as parameter to a block of memory, as fast as possible.
list | The top of the list |
dest | The destination block of memory |
max | The number of 32-bit words allocated in "dest" |

uint32_t eformat::write::count | ( | const node_t & | list | ) |
Counts how many pages I'm made of
list | The top of the list |

uint32_t eformat::write::count_words | ( | const node_t & | list | ) |
Sets an IOV base values
i | the node to be set |
b | the base address to be used by this IOV |
l | the size of the page, in words |
n | the next node this node should point to |

uint32_t eformat::write::shallow_copy | ( | const node_t & | list, |
struct iovec * | dest, | ||
uint32_t | max | ||
) |
Performs a shallow copy like operation, concatenating the list given as parameter to a vector of iovec nodes. This will only copy pointers and sizes, but not real data.
list | The top of the list |
dest | The destination vector of iovec nodes |
max | The number of iovec nodes I can use there |
