14.4.155  Winix_Pure_File_For_Os__Premicrothread

The standard library Winix_Pure_File_For_Os__Premicrothread api defines access to “pure” (side-effect free) input. (No attempt is made to implement pure output.)

Implementations of Winix_Pure_File_For_Os__Premicrothread are produced by winix_data_file_for_os_g__premicrothread and winix_text_file_for_os_g__premicrothread from respectively src/lib/std/src/io/winix-data-file-for-os-g–premicrothread.pkg and src/lib/std/src/io/winix-text-file-for-os-g–premicrothread.pkg.

Predefined packages generated by those two include the standard library winix_text_file_for_posix and winix_data_file_for_posix packages, more commonly referenced by the synonymous packages file and data_file.

The Winix_Pure_File_For_Os__Premicrothread api source code is in src/lib/std/src/io/winix-pure-file-for-os–premicrothread.api.
