查看linux 錯誤碼的程式

為了方便查看Linux系統下的錯誤碼以及它的含義，寫了一個程式來列印這些資訊。

 

listerrno.c

#include <stdio.h><br />#include <stdlib.h><br />#include <errno.h></p><p>#define MAX_ERRNO 256</p><p>int main(int argc, char* argv[])<br />{<br /> int n = 0;</p><p> printf("----------------------- Errno --------------------/n");<br /> for(n=0; n < MAX_ERRNO; n++)<br /> {<br /> printf("#%d, %s/n", n, strerror(n));<br /> }<br /> printf("--------------------------------------------------/n");</p><p> return 0;<br />}

 

Makefile：

E_TARGET = listerrno</p><p>all: $(E_TARGET)</p><p>listerrno:<br /> gcc -o $@ listerrno.c</p><p>clean:<br /> rm -rf $(E_TARGET) *.o
