What is the difference between mblen and strlen?
Is today multi-byte character encoding used in Windows, Linux or Mac OS? Is multi-byte character encoding same as fixed-width character encoding in Windows?
strlentakes the length of aconst char *, and assumes that onechartakes one byte, so it counts the chars until a null terminator (‘\0’) has been encountered, whereasmblentakes a pointer also of typeconst char *, but this points to the first byte of the multi byte character.For more info on what are multi-bye characters, have a look at this question.
