I don't seem to have it on my x86_64 Ubuntu machine but it exists in Arch, and I can't seem to find anyone or thing who knows what it does. 回答1: This is a tricky one; but it's the 64-bit version (whatever that means) of prlimit() ; a Linux-specific function in the getrlimit(2) family. It does not appear to be useful for 64-bit applications, as it relates to emulation of a 64-bit environment when one isn't available. 回答2: prlimit allows
