intro - 介紹系統(tǒng)調用

描述

本手冊的第二部分描述了Linux的系統(tǒng)調用。系統(tǒng)調用是一個入口點到Linux內核中。通常情況下，系統(tǒng)調用不直接調用：相反，大多數(shù)系統(tǒng)調用都有相應的C庫函數(shù)的包裝而執(zhí)行所需的步驟（例如，捕獲到內核模式），以便調用系統(tǒng)調用。因此，做一個系統(tǒng)調用看起來一樣調用一個正常的庫函數(shù)。

對于Linux系統(tǒng)調用列表，請參閱 syscalls(2).

返回值

On error, most system calls return a negative error number (i.e., the negated value of one of the constants described in errno(3)). The C library wrapper hides this detail from the caller: when a system call returns a negative value, the wrapper copies the absolute value into the errno variable, and returns -1 as the return value of the wrapper.

一個成功的系統(tǒng)調用返回的值取決于調用。許多系統(tǒng)調用返回0表示成功，但有些可以從一個成功的調用返回非零值。詳情載于個別的手冊頁描述。

In some cases, the programmer must define a feature test macro in order to obtain the declaration of a system call from the header file specified in the man page SYNOPSIS section. In such cases, the required macro is described in the man page. For further information on feature test macros, see feature_test_macros(7).

遵循于

某些術語和縮寫用于指示的Unix變體和標準在本節(jié)所謂符合?？?span style="color: rgb(0, 0, 0); font-family: verdana, helvetica, arial, sans-serif;"> standards(7).

注意

直接調用

In most cases, it is unnecessary to invoke a system call directly, but there are times when the Standard C library does not implement a nice wrapper function for you. In this case, the programmer must manually invoke the system call using syscall(2). Historically, this was also possible using one of the _syscall macros described in_syscall(2).
