cp and rm return non zero value
rm and cp return non zero values sometimes.
sprintf(tmp, "rm -rf %s/* 2>/dev/null\n", dest);
rc = system( tmp );
rc = 1 and errno =0
sprintf(tmp, "cp -r %s/* %s 2>/dev/null", source, dest);
rc = system( tmp );
rc = -1 and errno = 2.
The files exist and the paths are correct. I can do a manual copy but the application fails. If I restart the application, this works fine.
Can anyone tell why this could happen?

wsprintf
wsprintf(3C) Standard C Library Functions wsprintf(3C)
NAME
wsprintf - formatted output conversion
SYNOPSIS
#include <stdio.h>
#include <widec.h>
int wsprintf(wchar_t *s, const char *format, /* arg */ ... ););
DESCRIPTION
The wsprintf() function outputs a Process Code string ending with a Process Code (wchar_t) null character. It is the user's responsibility
to allocate enough space for this wchar_t string.
This returns the number of Process Code characters (excluding the null terminator) that have been written. The conversion specifications
and behavior of wsprintf() are the same as the regular sprintf(3C) function except that the result is a Process Code string for wsprintf(),
and on Extended Unix Code (EUC) character string for sprintf().
RETURN VALUES
Upon successful completion, wsprintf() returns the number of characters printed. Otherwise, a negative value is returned.
