#define	error_exit(error)
	A macro that prints the error msg and exit.
#define	error_ret(error)
	A macro that prints the error msg and return -1.
#define	unix_error_exit(error)
	A macro that prints the error msg(with errno) and then exit. I put 'unix' before the 'function' name because I am using 'errno'.
#define	unix_error_ret(error)
	A macro that prints the error msg(with errno) and then return -1. I put 'unix' before the 'function' name because I am using 'errno'.
#define	unix_print_error(error)
	A macro that prints the error msg(with errno) and then exit. I put 'unix' before the 'function' name because I am using 'errno'. This error handle(detail version) can show the `file`, `function` and `line` where the error happens.
#define	DEBUG 1
#define	debug_msg(fmt,...) fprintf(stdout, fmt, ##__VA_ARGS__)
	A macro that prints the debug msg, as the same with printf.
#define	TRACE 1
#define	debug_trace(trace)
	A macro that traces the `file`, `function` and `line`.

#define DEBUG 1

we debug all the time

#define debug_trace ( trace )

值:

fprintf(stdout, "%s File:%s Line:%d Func:%s.\n",   \
            trace, __FILE__, __LINE__, __func__)

A macro that traces the file, function and line.

#define error_exit ( error )

值:

do{                                         \
        fprintf(stderr, "%s\n", error);         \
        exit(0);                                \
    } while(0)

A macro that prints the error msg and exit.

#define error_ret ( error )

值:

do{                                           \
        fprintf(stderr, "%s\n", error);           \
        return -1;                                \
    } while(0)

A macro that prints the error msg and return -1.

#define TRACE 1

we trace all the time

#define unix_error_exit ( error )

值:

do{                                         \
        fprintf(stderr, "%s Info[%d]:%s\n",     \
                error, errno, strerror(errno)); \
        exit(1);                                \
    } while(0)

A macro that prints the error msg(with errno) and then exit. I put 'unix' before the 'function' name because I am using 'errno'.

#define unix_error_ret ( error )

值:

do{                                         \
        fprintf(stderr, "%s Info[%d]:%s\n",     \
                error, errno, strerror(errno)); \
        return -1;                              \
    } while(0)

A macro that prints the error msg(with errno) and then return -1. I put 'unix' before the 'function' name because I am using 'errno'.

#define unix_print_error ( error )

值:

do {                                                        \
        fprintf(stderr, "Oh God!\nFile:%s Line:%d Function:%s:\n",  \
                __FILE__, __LINE__, __func__);                      \
        perror(error);                                              \
        exit(0);                                                    \
    } while(0)

A macro that prints the error msg(with errno) and then exit. I put 'unix' before the 'function' name because I am using 'errno'. This error handle(detail version) can show the file, function and line where the error happens.

注解:: I do not often use this 'function' in my program.
