## @deftypefn {Function File} {} strcmp (@var{s1}, @var{s2})
## Compares two strings, returning 1 if they are the same, and 0 otherwise.
##
## @strong{Note:} For compatibility with @sc{Matlab}, Octave's strcmp
## function returns 1 if the strings are equal, and 0 otherwise. This is
## just the opposite of the corresponding C library function.
