Function Documentation

◆ Resource_GetInternalResource()

void Resource_GetInternalResource ( void )

Get internal resource of the current task if one is assigned.

Definition at line 161 of file Resource.c.

Here is the caller graph for this function:

◆ Resource_GetResource()

StatusType Resource_GetResource ( ResourceType ResID )

Request a resource.

This call serves to enter critical sections in the code that are assigned to the resource referenced by ResID. A critical section shall always be left using Resource_ReleaseResource().

Parameters

ResID Reference to resource

Returns: E_OK No error
E_OS_ID Invalid resource ID
E_OS_ACCESS Attempt to get a resource which is already occupied by any task or ISR, or the statically assigned priority of the calling task or interrupt routine is higher than the calculated ceiling priority

Definition at line 21 of file Resource.c.

◆ Resource_ReleaseInternalResource()

void Resource_ReleaseInternalResource ( void )

Release internal resource of the current task if one is assigned.

Warning: This function should only be called with interrupts disabled!

Definition at line 174 of file Resource.c.

Here is the caller graph for this function:

◆ Resource_ReleaseResource()

StatusType Resource_ReleaseResource ( ResourceType ResID )

Release a resource.

This function is the counterpart of Resource_GetResource() and serves to leave critical sections in the code that are assigned to the resource referenced by ResID.
