Function Documentation

void close_del_file	(	FILE *	fp,
		const char *	file
	)

void close_file

(

FILE *

fp

)

int date_diff	(	const char *	d1,
		const char *	d2
	)

diff two date-value and returns in seconds.

(Unix-ware required.)

Parameters:

	d1	a YYYYMMDD string.
	d2	a YYYYMMDD string.

void err_exit

(

int

ec

)

when error occurred, log current time and exit.

long ipow10

(

int

x

)

get [x]'s power of 10, an integer version.

bool is_empty

(

const char *

s

)

returns true if [s] contains no elements.

bool is_numeric

(

const char *

p

)

returns true if and only if [s] contains digits.

time_t make_time	(	const char *	sdate,
		const char *	fmt
	)

makes a time_t object with specified date and format.

(Unix-ware required.)

actually this is a wrapper of [strptime()].

Parameters:

	sdate	date-value in string format.
	fmt	date_format in string format.

FILE* open_file	(	const char *	file,
		const char *	mode
	)

char* ora_substr	(	const char *	s,
		int	n,
		unsigned int	m
	)

Returns a portion of [s], beginning at index [n], [m] characters long.

If [m] is positive, counts from the beginning of char to find the first character. if [m] is negative, counts backwards from the end of char. If [m] is omitted, returns all characters to the end of char.

Parameters:

	file	path of property file
	key	the key you want to find
	value	the value returned.

Examples:

testcase.pc.

void replace	(	const char *	in,
