Hi Team,
Recently, I came across an error "dereferencing pointer to incomplete type struct os_pool_cb " when in my program, I tried to access "markers" ( member of the struct os_pool_cb). Below is my design
file1.c
=======
#[include "cmsis_os.h"]
extern osPoolId mypool;
osPoolDef(rxDataPool, 16, sizeof(int));
mypool = osPoolCreate(osPool(rxDataPool));
if(mypool->markers) <=====(dereferencing pointer to incomplete type struct os_pool_cb)
file2.c
======
#[include "cmsis_os.h"]
osPoolId mypool;
uint32_t *ptr;
ptr = (uint32_t *)osPoolAlloc(mypool);
osPoolFree(mypool, ptr);
Solution
