query_module請求和可加載模塊有關的來自核心的信息.信息的細-
P的特性和格式依賴於 which參數,一些函數-
n求name參數來命名當前被加載的模塊.一些允陸捊躪ame為null,
指明核心是正確的.: which的 0 Always returns success. Used to probe
for the system call. 0 總是返回成孕峔荓斐系統調用. /* 參見 insmod
-p 和前惜撜 */ QM_MODULES Returns the names of all loaded
modules. The output buffer
format is adjacent null-terminated strings; ret is set to the number
of mod ules.
返回所有已加載的模塊的名字.輸出緩沖區的格式是鄰近的以null終止的字符串;ret
被 設置為模塊的數目. QM_DEPS Returns the names of all modules
used by the indicated module. The output buffer format is adjacent
null-terminated strings; ret is set t o the number of modules.
返回所有被name參數指定的模塊使用的模塊的名字.輸出 緩
沖區格式是鄰近的以null終止的字符串;ret被設置為模塊的數目. QM_REFS
Returns the names of all modules using the indicated module. This is
the inverse of QM_DEPS. The output buffer format is adjacent null-te
rminated strings; ret is set to the number of modules.
返回所有正使用被name參數指定的模塊的模塊名字.這和QM_DEPS是相反的.輸出緩沖
區 格式是以鄰近的null終止的字符串;ret被設置為模塊的數目. QM_SYMBOLS
Returns the symbols and values exported by the kernel or t he indicated
module. The buffer format is an array of:
struct module_symbol
{
unsigned long value;
unsigned long name;
};
followed by null-terminated strings. The value of name is
the character offset of the string relative to the start of buf; ret is
set to t he number of symbols.
返回被核心或指定模塊導出(開放)的符號和.緩沖區格式是一-
茈Hnull終止的 結構數組,name的-
O相對緩沖區的開始的字符串的字符偏移;ret被設置為符號的數目.
struct module_symbol
{
unsigned long value;
unsigned long value;
} QM_INFO Returns miscelaneous information about the
indicated module. The output buffer format is:
struct module_info
{
unsigned long address;
unsigned long size;
unsigned long flags;
};
where address is the kernel address at which the module
reside s, size is the size of the module in bytes, and flags is a mask
of MOD_RUNNI NG, MOD_AUTOCLEAN, et al that indicates the current status
of the module. re t is set to the size of the module_info
struct.
返回各種和指定模塊相關的各種信息,輸出緩沖區的格式如下:
struct module_info
{
unsigned long address;
unsigned long size;
unsigned long flags;
}
address是模塊在核心空間中駐留的地址,size是模塊以字節-
p數的大小,flags是MOD_R
UNING,MOD_AUTOCLEAN等指示模塊當前狀態的標誌的按位或組成的掩瑪.ret被設置為mod
ule_info結構的大小.
^
成幼匢`是返回0,錯誤是返回-1,全局變量errno被相應設置.
~
ENOENT 被name指定的模塊不存在.
EINVAL
ENOSPC 提供的緩沖區太小,ret被設置為需n的最小大小.
EFAULT name,buf或ret中至少一荈V出了程式可訪問的地址空間.
