Macro Definition Documentation

◆ LWIP_COMPAT_MUTEX

#define LWIP_COMPAT_MUTEX   0

Define LWIP_COMPAT_MUTEX if the port has no mutexes and binary semaphores should be used instead

Definition at line 108 of file sys.h.

◆ SYS_ARCH_DEC

#define SYS_ARCH_DEC (   var,
  val 
)
Value:
do { \
SYS_ARCH_DECL_PROTECT(old_level); \
SYS_ARCH_PROTECT(old_level); \
var -= val; \
SYS_ARCH_UNPROTECT(old_level); \
} while(0)
val
GLuint GLfloat * val
Definition: glext.h:7180
var
const char * var
Definition: shader.c:5666

Definition at line 535 of file sys.h.

◆ SYS_ARCH_DECL_PROTECT

#define SYS_ARCH_DECL_PROTECT (   lev)

SYS_LIGHTWEIGHT_PROT define SYS_LIGHTWEIGHT_PROT in lwipopts.h if you want inter-task protection for certain critical regions during buffer allocation, deallocation and memory allocation and deallocation.

Definition at line 512 of file sys.h.

◆ SYS_ARCH_GET

#define SYS_ARCH_GET (   var,
  ret 
)
Value:
do { \
SYS_ARCH_DECL_PROTECT(old_level); \
SYS_ARCH_PROTECT(old_level); \
ret = var; \
SYS_ARCH_UNPROTECT(old_level); \
} while(0)
ret
return ret
Definition: mutex.c:146

Definition at line 544 of file sys.h.

◆ SYS_ARCH_INC

#define SYS_ARCH_INC (   var,
  val 
)
Value:
do { \
SYS_ARCH_DECL_PROTECT(old_level); \
SYS_ARCH_PROTECT(old_level); \
var += val; \
SYS_ARCH_UNPROTECT(old_level); \
} while(0)

Definition at line 526 of file sys.h.

◆ SYS_ARCH_LOCKED

#define SYS_ARCH_LOCKED (   code)
Value:
do { \
SYS_ARCH_DECL_PROTECT(old_level); \
SYS_ARCH_PROTECT(old_level); \
code; \
SYS_ARCH_UNPROTECT(old_level); \
} while(0)
code
Definition: inflate.c:139

Definition at line 562 of file sys.h.

◆ SYS_ARCH_PROTECT

#define SYS_ARCH_PROTECT (   lev)

Definition at line 513 of file sys.h.

◆ SYS_ARCH_SET

#define SYS_ARCH_SET (   var,
  val 
)
Value:
do { \
SYS_ARCH_DECL_PROTECT(old_level); \
SYS_ARCH_PROTECT(old_level); \
var = val; \
SYS_ARCH_UNPROTECT(old_level); \
} while(0)

Definition at line 553 of file sys.h.

◆ SYS_ARCH_TIMEOUT

#define SYS_ARCH_TIMEOUT   0xffffffffUL

Return code for timeouts from sys_arch_mbox_fetch and sys_arch_sem_wait

Definition at line 87 of file sys.h.

◆ SYS_ARCH_UNPROTECT

#define SYS_ARCH_UNPROTECT (   lev)

Definition at line 514 of file sys.h.

◆ SYS_MBOX_EMPTY

#define SYS_MBOX_EMPTY   SYS_ARCH_TIMEOUT

sys_mbox_tryfetch() returns SYS_MBOX_EMPTY if appropriate. For now we use the same magic value, but we allow this to change in future.

Definition at line 92 of file sys.h.

◆ sys_mbox_fetch

#define sys_mbox_fetch (   mbox,
  msg 
)    sys_arch_mbox_fetch(mbox, msg, 0)

Definition at line 370 of file sys.h.

◆ sys_mbox_set_invalid_val

#define sys_mbox_set_invalid_val (   mbox)    sys_mbox_set_invalid(&(mbox))

Same as sys_mbox_set_invalid() but taking a value, not a pointer

Definition at line 401 of file sys.h.

◆ sys_mbox_tryfetch

#define sys_mbox_tryfetch (   mbox,
  msg 
)    sys_arch_mbox_tryfetch(mbox, msg)

For now, we map straight to sys_arch implementation.

Definition at line 360 of file sys.h.

◆ sys_mbox_valid_val

#define sys_mbox_valid_val (   mbox)    sys_mbox_valid(&(mbox))

Same as sys_mbox_valid() but taking a value, not a pointer

Definition at line 395 of file sys.h.

◆ sys_sem_set_invalid_val

#define sys_sem_set_invalid_val (   sem)    sys_sem_set_invalid(&(sem))

Same as sys_sem_set_invalid() but taking a value, not a pointer

Definition at line 258 of file sys.h.

◆ sys_sem_valid_val

#define sys_sem_valid_val (   sem)    sys_sem_valid(&(sem))

Same as sys_sem_valid() but taking a value, not a pointer

Definition at line 252 of file sys.h.

◆ sys_sem_wait

#define sys_sem_wait (   sem)    sys_arch_sem_wait(sem, 0)

Wait for a semaphore - forever/no timeout

Definition at line 227 of file sys.h.

Typedef Documentation

◆ lwip_thread_fn

typedef void(* lwip_thread_fn) (void *arg)

Function prototype for thread functions

Definition at line 98 of file sys.h.

◆ sys_jiffies()

u32_t sys_jiffies ( void  )
