Program for viewing Linux error codes

In order to conveniently view the error code and its meaning in Linux, a program is written to print the information.

 

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
