FUNCTIONS

sprintf

Usage:

 sprintf(%args) -> [status, msg, payload, 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.

This function is not exported.

Arguments ('*' denotes required arguments):

format* => str
in => array
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)

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 (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)
