### Description

This block allows user to read data in a C file. Output record selection and Time record Selection allows the user to select data among file records. Each call to the block advance one record in the file.

### Dialog box

- Time record selection
  an empty matrix or a positive integer.
  If an integer i is given the i th element of the read record is assumed to be the date of the output event.
  If empty no output event exists.
  Properties : Type 'vec' of size -1

- Outputs record selection
  a vector of positive integer.
  ,The th element of the read record gives the value of output.
  Properties : Type 'vec' of size -1

- Input file name
  a character string defining the path of the file.
  Properties : Type 'str' of size 1

- Input Format
  a character string defining the format to use.
  Properties : Type 'str' of size 1

- Record size
  The file is supposed to be formed by a sequence of data with same format.
  These data are organized in a sequence of record each of them containing Record size data.
  Properties : Type 'vec' of size 1

- Buffer size
  To improve efficiency it is possible to buffer the input data. Read on the file is only done after each Buffer size call to the block.
  Properties : Type 'vec' of size 1

- Initial record index
  a scalar. This fixes the first record of the file to use.
  Properties : Type 'vec' of size 1

- Swap mode 0/1
  With Swap mode=1 the file is supposed to be coded in "little endian IEEE format" and data are swaped if necessary to match the IEEE format of the processor. If Swap mode=0 then automatic bytes swap is disabled.
  Properties : Type 'vec' of size 1

### Default properties

- always active: no

- zero-crossing: no
- mode: no
- regular outputs:
  - port 1 : size [1,1] / type 1
- number/sizes of activation inputs: 1
- number/sizes of activation outputs: 0
- continuous-time state: no
- discrete-time state: yes
- object discrete-time state: no
- name of computational function: readc
