Function memfd_create [src]

Prototype

pub fn memfd_create(name: []const u8, flags: u32) MemFdCreateError!fd_t

Parameters

name: []const u8flags: u32

Possible Errors

NameTooLong

Either the name provided exceeded NAME_MAX, or invalid flags were passed.

OutOfMemory

ProcessFdQuotaExceeded

SystemFdQuotaExceeded

SystemOutdated

Unexpected UnexpectedError

The Operating System returned an undocumented error code.

This error is in theory not possible, but it would be better to handle this error than to invoke undefined behavior.

When this error code is observed, it usually means the Zig Standard Library needs a small patch to add the error code to the error set for the respective function.

    @memcpy(buffer[0..name.len], name);
    buffer[name.len] = 0;
