memcpy.2: missing restrict keyword

memcpy.2: missing restrict keyword

[Heinrich Schuchardt]

Hello Michael,

Since C99 the memcpy is defined as

void *memcpy(void* restrict dst, const void* restrict src, size_t n);

Shouldn't the restrict keyword be shown in the prototype on the man-page?

Other concerned functions include:

memccpy(), strcat(), strncat, strcpy(), strncpy(), strxfrm(), strtok(),
strtok_r(), printf()-family, fcvt_r(), strtoimax()-family,
getmntent_r(), ...

Just grep for restrict in the standard includes.

Best regards

Heinrich

Hi Heinrich,

I agree.  That's on my todo list.

I'm first fixing the prototypes for syscalls, which have significant
deviations, then I'll have a look at glibc wrappers, and then I'll fix
glibc library calls.

Thanks,

Alex
