Function Documentation

void di_free (  void *  mem  )

Free memory Parameters: mem  memory { free (mem); }

void* di_malloc (  size_t  n_bytes  )

Allocate memory Parameters: n_bytes  size in bytes Postcondition: never returns NULL { void *mem; mem = malloc (n_bytes); if (!mem) di_error ("%s: failed to allocate %zu bytes", DI_STRLOC, n_bytes); return mem; }

void* di_malloc0 (  size_t  n_bytes  )

Allocate cleared memory Parameters: n_bytes  size in bytes Postcondition: never returns NULL { void *mem; mem = calloc (1, n_bytes); if (!mem) di_error ("%s: failed to allocate %zu bytes", DI_STRLOC, n_bytes); return mem; }
