Detailed Description

Comparison functions for strings.

Function Documentation

string_compare()

int string_compare	(	void *	string1,
		void *	string2 )

Compare two strings.

Parameters

string1	The first string.
string2	The second string.

Returns

A negative value if the first string should be sorted before the second, a positive value if the first string should be sorted after the second, zero if the two strings are equal.

string_equal()

int string_equal	(	void *	string1,
		void *	string2 )

Compare two strings to determine if they are equal.

Parameters

string1	The first string.
string2	The second string.

Returns

Non-zero if the strings are equal, zero if they are not equal.

string_nocase_compare()

int string_nocase_compare	(	void *	string1,
		void *	string2 )

Compare two strings, ignoring the case of letters.

Parameters

string1	The first string.
string2	The second string.

Returns

A negative value if the first string should be sorted before the second, a positive value if the first string should be sorted after the second, zero if the two strings are equal.

string_nocase_equal()

int string_nocase_equal	(	void *	string1,
		void *	string2 )

Compare two strings to determine if they are equal, ignoring the case of letters.

Parameters

string1	The first string.
string2	The second string.

Returns

Non-zero if the strings are equal, zero if they are not equal.
