static method _IOLBF : int ();
static method _IOFBF : int ();
* Added the offset argument to the following methods.
[Before]
static method read : int ($fd : int, $buf : mutable string, $count : int);
static method write : int ($fd : int, $buf : string, $count : int);
static method fread : int ($ptr : mutable string, $size : int, $nmemb : int, $stream : Sys::IO::FileStream);
static method fgets : mutable string ($s : mutable string, $size : int, $stream : Sys::IO::FileStream);
static method fwrite : int ($ptr : string, $size : int, $nmemb : int, $stream : Sys::IO::FileStream);
[After]
static method read : int ($fd : int, $buf : mutable string, $count : int, $buf_offset = 0 : int);
static method write : int ($fd : int, $buf : string, $count : int, $buf_offset = 0 : int);
static method fread : int ($ptr : mutable string, $size : int, $nmemb : int, $stream : Sys::IO::FileStream, $ptr_offset = 0 : int);
static method fgets : mutable string ($s : mutable string, $size : int, $stream : Sys::IO::FileStream, $s_offset = 0 : int);
static method fwrite : int ($ptr : string, $size : int, $nmemb : int, $stream : Sys::IO::FileStream, $ptr_offset = 0 : int);
什么是 SPVM？
SPVM是一种静态类型语言，可以从Perl使用。SPVM是 Python/numpy 移植到 Perl 的重要组成部分。如果你还没有听说过Perl的SPVM。另请参阅SPVM 语言规范。SPVM的潜在剂量有多大？
预计生物技术，AI / ML，Apple/iPhone / iPad应用程序，Google/Android应用程序，物联网设备，联网汽车，智能设备，智能家居等领域将增长。
这是因为SPVM可以生成支持跨平台的可执行文件，并且可以轻松计算数组和绑定C / C++和Nvidia / GPU / cuda。
