| parent | Add cast to uint32_t to allow 16bit shift on 16bit-int targets. (diff) | |
| download | rtems-2334ea19ae85cab636b0ae035661e49526cac145.tar.bz2 | |
Add HAVE_CONFIG_H guard.
Include <limits.h>. Shift pid_t's by (sizeof(pid_t)*CHAR_BIT)>>1
instead of hard-coded 16 to permit building on non 16bit-int
targets.
