NAME ^

Perinci::Examples::FilePartial - Examples for reading/writing files (demos partial argument/result)

VERSION ^

This document describes version 0.80 of Perinci::Examples::FilePartial (from Perl distribution Perinci-Examples), released on 2017-07-11.

DESCRIPTION ^

The functions in this package demoes partial content upload as well as partial result.

The functions are separated into this module because these functions read/write files on the filesystem and might potentially be dangerous if Perinci::Examples is exposed to the network by accident.

See also Perinci::Examples::FileStream which uses streaming instead of partial.

FUNCTIONS ^

append_file

Usage:

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

This function doesn't actually accept partial content, because by nature it is already a partial/incremental operation.

This function is not exported.

Arguments ('*' denotes required arguments):

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.

Return value: (any)

read_file

Usage:

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

This function is not exported.

Arguments ('*' denotes required arguments):

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.

Return value: (buf)
