Why fgets() does not update properly the file pointer when the file being read was opened in text mode and its respective lines teminate with a single &lt;LF&gt; instead of &gt;CR&gt;&lt;LF&gt;? What can be expected to happen and why? I got several different results like fgets returning NULL or wrong value for current file pointer as returned by ftell().

fgets in Borland C

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
