Take a look at fgets().

From the HP C/iX Library Reference Manual:

  Syntax

    #include <stdio.h>
    char *fgets (char *string, int n, FILE *stream);

  Description

    The fgets() function reads a string from an open stream. The string
    parameter is a pointer to a character string, and stream is a file
    pointer to the input stream

    The fgets() function reads n-1 characters up to a newline character,
    whichever comes first....
    ...

Sounds to me like if you used fgets() with n=2, then the read should
terminate after the first character. At least that's how I interpret it,
but I haven't actually tested it.
