fgets()

This is a File I/O function. It is not implemented in the Compiler.

  #include <stdio.h>

    char *fgets(char *s, int n, FILE *f);

fgets() reads a string of at most n-1 characters from file f into s. Immediately after the last character read, a '\0' is appended. If fgets() reads a line break ( '\n') or reaches the end of the file before having read n-1 characters, the following happens:

• If fgets() reads a line break, it adds the '\n' plus a '\0' to s and returns successfully.
• If it reaches the end of the file after having read at least 1 character, it adds a '\0' to s and returns successfully.
• If it reaches EOF without having read any character, it sets the file's end-of-file flag and returns unsuccessfully. ( s is left unchanged.)

NULL, if there was an error; s otherwise.
