strtoul

Parse an unsigned integer from the start of a string, in a given base.

תקציר

use POSIX qw(strtoul);
my ($n, $unparsed) = strtoul("255 end", 10);

מקרי קצה

• Invalid base: returns (undef, undef) and sets $! to EINVAL.

• Negative input: parsed and two’s-complement-cast to unsigned, matching C strtoul.
