Hi !
Sorry for the inconvenience, I wanted to know if this
piece of code seemed to be correct for a OpenBSD developer ?
#define SAFE_FREE(addr) do { \
if (addr) \
{ \
free (addr); \
addr = NULL; \
} \
else \
{ \
fprintf (stderr, " (double free inside %s:%s) at L%d\n", \
__FILE__, __func__, __LINE__); \
} \
} while(0);
char *
argv_into_line (char **args)
{
if (args == NULL)
return NULL;
size_t offset = 0;
char **s = args;
char *line = NULL;
for (; *s; ++s)
{
const size_t len = strlen (*s);
// pour l'espace et le terminateur
char *new_line = realloc (line, len + offset + 2);
if (new_line == NULL)
{
if (line != NULL)
{
SAFE_FREE (line);
}
break;
}
line = new_line;
memset (&line[offset], 0, len);
strcat (strcat (&line[offset], *s), " ");
offset += len + 1 ;
}
return line;
}
