open_rawresource(3) Arcan Lua API open_rawresource(3) NAME open_rawresource - Open a private or shared resource for reading/writing SYNOPSIS success_bool open_rawresource( resstr ) DESCRIPTION Each session can have one- globally opened and synchronously managed text file for working with in a rather limited fashion, primarily intended for debugging or quick temporary hacks. Typically, user/appl data should be stored in the database if at all possible, and binary data should only be in forms that the indirect functions can working with (like load_image etc.). Other I/O operations e.g. named pipes should go through the open_nonblock style functions. NOTES 1 If the resource exists, it will be opened in a read-only mode. 2 If the resource doesn't exist, it will be created and opened for writing (in appl, shared resources are read-only). 3 This function is blocking, and should only be used where possible I/O stalls is desired. EXAMPLE function open_rawresource0() if (open_rawresource("test.txt")) then print("resource opened"); else print("couldn't open resource"); end end MISUSE function open_rawresource0() if (open_rawresource("../../../../../../../etc/passwd")) then print("danger will robinson!"); end end SEE ALSO: close_rawresource(3) read_rawresource(3) zap_rawresource(3) open_non- block(3) resource August 2026 open_rawresource(3)
