DESCRIPTION
FUNCTIONS
None are exported by default, but they are exportable.
sprintf(%args) -> [status, msg, result, meta]
Array will also be processed (all the elements are fed to sprintf(), the result is a single string), unless skip_array
is set to true.
Non-numbers can be skipped if you use skip_non_number
.
Undef, hashes, and other non-scalars are ignored.
Arguments ('*' denotes required arguments):
format* => str
in => any
Input stream (e.g. array or filehandle).
out => any
Output stream (e.g. array or filehandle).
skip_array => bool (default: 0)
skip_non_number => bool (default: 0)
Return value:
Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
