block_t* block_File

(

fd

)

Loads a file into a block of memory.

If possible a private file mapping is created. Otherwise, the file is read normally. On 32-bits platforms, this function will not work for very large files, due to memory space constraints.

Parameters:

fd

file descriptor to load from

Returns:

a new block with the file content at p_buffer, and file length at i_buffer (release it with block_Release()), or NULL upon error (see errno).
