fgets

#include <stdio.h>

char *fgets  (
    char* string,      /* store string */
    int   length,      /* length of string */
    FILE* stream);     /* file stream to read from */

The function fgets reads a string from a data steam. The parameter string is a pointer defining the buffer to store the string. The parameter length defines the numbers of characters to read. The parameter stream is a pointer defining the data stream to read from.

The function is included in the library RL-FlashFS. The prototype is defined in the file stdio.h

Characters are read from the current cursor position:

• until length characters have been read.
• up to and including the first new-line ('\n').
• up to the end of the stream.

A null character ('\0') is appended to string.

• string - on success.
• NULL - on error or end-of-file condition.
