[Octave-bug-tracker] [bug #57879] strncmp(str_a, str_b, N) gives an error for N=0

[Nicholas Jankowski]

Follow-up Comment #2, bug #57879 (project octave):

and that is spelled out in the matlab help, so this is a documented
compatibility bug


If n is 0, then strncmp always returns 1. By convention, the zeroth character
of a character vector or a string scalar is always '', a 0-by-0 character
array.

If n is less than 0, then strncmp treats it as 0.
