	)		[static]

Definition at line 407 of file fstrcmp.c.

double explain_fstrcasecmp	(	const char *	s1,
		const char *	s2
	)

The explain_fstrcasecmp function may be used to compare two strings. The comparison is case insensitive. The order of the strings has no effect on the result.

Parameters:

s1	The first string to be compared.
s2	The second string to be compared.

Returns:

Rather than a simple yes/no result, the similarity of the strings is returned. A return of 0.0 means the strings are completely differemt, and a return value of 1.0 means they are identical. However, values can be returned between these two values, indicating the degree of similarity.

Note:

This function uses dynamic memory. May return -1 if malloc fails.
