Detailed Description

Field Documentation

◆ buffer

unsigned char* _struct_IO_BUFFER::buffer

◆ buflen

long _struct_IO_BUFFER::buflen

◆ byte_order

int _struct_IO_BUFFER::byte_order

◆ data

BYTE* _struct_IO_BUFFER::data

◆ extended

int _struct_IO_BUFFER::extended

◆ input_file

FILE* _struct_IO_BUFFER::input_file

◆ input_fileno

int _struct_IO_BUFFER::input_fileno

◆ is_allocated

int _struct_IO_BUFFER::is_allocated

It is 1 if buffer is allocated by eventio, 0 if buffer provided by user function (in which case the user should call allocate_io_buffer with the appropriate size; then the buffer always allocated in allocate_io_buffer() must be freed by the user function, replaced by its external buffer, and finally is_allocated set to 0).

◆ item_extension

int _struct_IO_BUFFER::item_extension[MAX_IO_ITEM_LEVEL]

◆ item_level

int _struct_IO_BUFFER::item_level

◆ item_start_offset

long _struct_IO_BUFFER::item_start_offset[MAX_IO_ITEM_LEVEL]

◆ output_file

◆ sync_err_count

◆ sync_err_max

int _struct_IO_BUFFER::sync_err_max

◆ user_function

int(* _struct_IO_BUFFER::user_function) (unsigned char *, long, int)

◆ w_remaining
