Name

sqlite3_strnicmp() — Compare two strings while ignoring case [EXP]

Definition

int sqlite3_strnicmp( const char* textA, const char* textB, int lenth );
textA, textB

Two UTF-8 encoded strings.

length

The maximum number of characters to compare.

Returns

A negative value will be returned if textA < textB, a zero value will be returned if textA = textB, and a positive value will be returned if textA > textB.

Description

This function allows an application to compare two strings using the same case-independent logic that SQLite uses internally. Remember that this is an order comparison function, not an “is equal” function. A result of zero (which is often interpreted as false) indicates that the two strings are equivalent.

The ability to ignore letter case only applies to characters with a character code of 127 or less. The behavior of this function when using character codes greater than 255 is somewhat undefined.
