No, it's not present in string.h, as far as Splint is concerned.
string.h is a standard header (it's part of the library defined by the C
standard, ISO 9899). As such, it's provided by the implementation.
Splint is a C implementation, and it supplies its own standard headers -
it doesn't use some random file on your system just because it happens
to be named "string.h".
Splint's string.h conforms to the standard. The standard does not define
a function (or other identifier) named "bzero".
You probably have some other C implementation (or something C-like, such
as GCC run in non-compliant mode) on your system, and it probably
provided a string.h that includes, in addition to the standard library
functions, a declaration for "bzero". Some implementations do this, for
historical reasons. Splint does not.
The best options for correcting this:
- Replace the use of bzero with memset in your code. bzero is
- Add the following declaration to all of your source files that contain
references to bzero:
extern void bzero(char *s, int n);
(That assumes your implementation's bzero matches that declaration.
There's no guarantee of that, since bzero is not standard.) It's best to
put that declaration in a header, if bzero is used in more than one
