inlinestatic

An atomic compare and set function used by the mutex functions. (Atomically) Equivalent to:

if (*dst == *exp)
  *dst = *src
else
  *exp = *dst

Note: This function is currently available for the x86-64 and aarch64 platforms.; The success and failure arguments must be one of the __ATOMIC_* values defined in the C++11 standard. For details on their behavior, refer to the standard.

Parameters

dst	The destination into which the value will be written.
exp	Pointer to the expected value. If the operation fails, this memory is updated with the actual value.
src	Pointer to the new value.
weak	A value of true allows the comparison to spuriously fail and allows the 'exp' update to occur non-atomically (i.e. a torn read may occur). Implementations may ignore this argument and only implement the strong variant.
success	If successful, the operation's memory behavior conforms to this (or a stronger) model.
failure	If unsuccessful, the operation's memory behavior conforms to this (or a stronger) model. This argument cannot be __ATOMIC_RELEASE, __ATOMIC_ACQ_REL, or a stronger model than success.

Returns: Non-zero on success; 0 on failure.
