int byte_extract (  int  endianess, int  bytes_to_grab, u_int8_t *  ptr, u_int8_t *  start, u_int8_t *  end, u_int32_t *  value )

Grab a binary representation of data from a buffer This method will read either a big or little endian value in binary data from the packet and return an u_int32_t value. Parameters: endianess  value to read the byte as bytes_to_grab  how many bytes should we grab from the packet data  pointer to where to grab the data from start  pointer to start range of buffer end  pointer to end range of buffer value  pointer to store data in Returns: 0 on success, otherwise failure Definition at line 52 of file byte_extract.c.

int string_extract (  int  bytes_to_grab, int  base, u_int8_t *  ptr, u_int8_t *  start, u_int8_t *  end, u_int32_t *  value )

Grab a string representation of data from a buffer Parameters: base  base representation for data: -> man stroul() bytes_to_grab  how many bytes should we grab from the packet data  pointer to where to grab the data from start  pointer to start range of buffer end  pointer to end range of buffer value  pointer to store data in Returns: 0 on success, otherwise failure Definition at line 129 of file byte_extract.c.
