fgets()

This is a file I/O function, also hardware dependent. It is not implemented in this 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, fgets() appends a '\0'. 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 an error occurred; s otherwise.
