Function Documentation

abbrev()

int abbrev	(	CONST char *	s,
		CONST char *	t
	)

s may be an abbreviation of t. Upper/lower case in s is ignored. s has to be at least as long as the leading upper case, digit, and '_' part of t.

Parameters

s	The string to be checked.
t	The test string with minimum part in upper case.

Returns

1 if s is an abbreviation of t, 0 if not.

getword()

int getword	(	CONST char *	s,
		int *	spos,
		char *	word,
		int	maxlen,
		char	blank,
		char	endchar
	)

The word must have a length less than or equal to maxlen.

Parameters

s	string with any number of words.
spos	position in the string where we start and end.
word	the extracted word.
maxlen	the maximum allowed length of word.
blank	has the same effect as ' ', i.e. end-of-word.
endchar	his terminates the whole string ( as '\0' ).

Returns

-2 : Invalid string or NULL -1 : The word was longer than maxlen (without the terminating '\0'); 0 : There were no more words in the string s. 1 : ok, we have a word and there are still more of them in the string s 2 : ok, but this was the last word

Here is the caller graph for this function:

stricmp()

int stricmp	(	CONST char *	a,
		CONST char *	b
	)

Parameters

a,b	– strings to be compared.

Returns

0 : strings are equal (except perhaps for case) >0 : a is lexically 'greater' than b <0 : a is lexically 'smaller' than b
