C code:
char jobname[10];
memcpy(jobname, " ", 10); /* this is line 131 */
Compilation errors:

Hi Harish,
Assuming there are no syntax errors prior to these lines I was guessing perhaps memcpy is undefined (lacking the header) but the undefined'edness would also be reported.
I'd guess 'memcpy' has been #defined incorrectly somewhere seems to me to be the next most likely option but it is distinctly rarer.
Lets see what JC has to say :-)
Paul
Since I got the following error message the memcpy function is defined; it just says I have missing arguments.
GC99999/C(STATUS), 131.19: CZM0182(30) Arguments missing for built-in function __memcpy.
Also the next statement is:
memcpy(prtfil, (((var_record_t *)\
lstptr2)->Data_Field),
(((Qus_LSPL_Key_Info_t *)lstptr2)\
->Data_Length));
and it doesn't get a compilation error.
Try this simple program :
----------
#include <stdlib.h>
int main(void) {
char test[10];
memcpy((void*) &test[0], (const void*) "test", (size_t) 5);
memcpy(&test[0], "test", 5);
memcpy(test, "test", 5);
return 0;
}
----------
And see if, and at what line the compiler gives an error.
If it doesn't give an error at all, then check whether you correctly included the header file containing the declaration of memcpy(void*, const void*, size_t), AND that there's no re-declaration of memcpy anywhere !!!
If there is a compiler error at one of the above lines, then change your code to match the last correct line's syntax.
If the first line in the above code also provokes a compiler error, then you might want to check if the standard library hasn't been corrupted somehow. What compiler are you using ?
