DESCRIPTION

FUNCTIONS

None are exported by default, but they are exportable.

sprintf(%args) -> [status, msg, result, meta]

Apply sprintf() on input.

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

• out => any

• 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.
