(

int

roff

)

int Scanp::scan	(	const char *	pat,
			...
	)

This routine scans a character string for data and parses information using a pattern description string.

Scans and decodes data

Parameters:

pat

Pattern to use Formatting similar to scanf except more robust: %{*}{<}{f}{!m!}t * Don't assign to a variable f Field width - match exactly this number of characters <f Field width - match up to this number of characters !m! Specifies that a missing value can be specified either is nothing or the string m t Format type -- s Standard string delimited by spaces -- S Match all characters - terminatint null character -- c Standard characters - no terminating null character -- A Alphabetic string only -- N Numeric string only -- n Current position in string -- d Integer -- D Integer, no white space skip -- f Floating point -- F Floating point, no white space skip -- w Whitespace -- W Whitespace, no newline -- (s) Match exact string -- (s|s|..) Match strings in this set of string delimited with | -- [s] Match character types or specific characters s = A for alphabetic, N for numeric, all others literal -- [^s] Match everythin but character types or specific characters Leading whitespace are not read on S,A,N,D or F formats. Non-format characters are literal except space which matches any number of whitespace characters.

int Scanp::search

(

const char *

rstr

)

Searches the current string for another string

Parameters:

rstr

String to search for

Returns:

1 if found, 0 if not

int Scanp::set

(

const char *

rstr

)

Sets the string to scan

Parameters:

rstr

Data string
