memset vs bzero

[puzzlecracker]

I have seen these two functions used interchangeably and could never
fully discern their meaning, nor could understand the particular
preference to either one.

Could someone be kind enough to explain that (or least to direct me to
a good source)?


thanks

bzero can only be used to reset memory location. Besides that bzero is
not a standard function.

The function bzero() does not exist in standard C. To use it you
have to define it first. Memset, on the other hand, pre-exists and
has a known meaning.

bzero was found on BSD unix, meset on AT&T unix. memset was
adopted by the ANSI C and POSIX standards and bzero deprecated.

please put your question entirely in the mesage body. Not all newsreaders
display the 'subject' line right next to the body, and you should not
expect your readers to have to bob about to discover what you're talking
about.

By the way, bzero is nonstandard, and you should use memset.

C has memset(), the Berkeley UNIX C library has bzero(). They are not
identical, and bzero() predates memset() but is not widely available (since
it's not part of standard C).

Well, it's supported on every Linux platform on the planet, if that
helps. :-)

which still doesn't count as widely available, for what its worth.

So it is quite useful for people who want to write Linux-only,
non-portable code instead of writing portable code.
