PC-Lint: undeclared funtion

[suppamax]

Hi everybody!

I'm using for the first time PC-Lint.

I'm analysing my C program for Microchip PIC18F
microcontroller.

In particualr I have a problem with library
functions like "memcpy" or "ltoa".

I've included <string.h> and <stdlib.h> in my
files, and I've added their path in my lin.bat file.

But it seems that PC-lint is unable to recognise
them, since I receive the following message

(void)memcpy((void *)&FailureBuffer.date,
(const void *)&g_CurrentTime, sizeof(timestamp_t));
...\source files\app_check.c 292 Info 718: Symbol
'memcpy' undeclared, assumed
to return int
...\source files\app_check.c 292 Info 746: call
to function 'memcpy()' not
made in the presence of a prototype

and

Warning 526: Symbol 'memcpy()' (line 292, file
...\source files\app_check.c) not
defined
...\source files\app_check.c 292 Info 830:
Location cited in prior message
Warning 628: no argument information provided for
function 'memcpy()' (line
292, file ..\source files\app_check.c)
...\source files\app_check.c 292 Info 830:
Location cited in prior message


What can I do?


Thanks,


Max

What can I do?

<ot>
Define the path variable so that pc-lint can find the headers.

It's in the documentation.

Others have addressed the lint problem. But why, if you have a
prototype in scope, are you casting the arguments to memcpy? It
cannot help and my even camouflage undefined behavior.
