osal_atomic.h

    Description:

    Declares atomic and bit operation interfaces.

    This file provides interfaces such as reading and setting an atomic, incrementing and decrementing an atomic counter by 1. This file also provides interfaces such as checking the bit status of a variable, and setting and clearing the bit value of a variable.

    Description

    OsalAtomicRead (const v)

    int32_t 

    Reads the counter of an atomic.

    OsalAtomicSet ( v, int32_t counter)

    void 

    Sets the counter for an atomic.

    OsalAtomicInc ( v)

    void 

    Increments the counter of an atomic by 1.

    void 

    Decrements the counter of an atomic by 1.

    OsalTestBit (unsigned long nr, const volatile unsigned long addr)

    int32_t 

    Tests the value of a specified bit of a variable.

    (unsigned long nr, volatile unsigned long addr)

    int32_t 

    Sets the value of a specified bit of the variable and returns the bit value before the setting.

    OsalTestClearBit (unsigned long nr, volatile unsigned long addr)

    int32_t 

    Clears the value of a specified bit of the variable and returns the bit value before clearing.

    (unsigned long nr, volatile unsigned long addr)

    Clears the value of a specified bit of the variable.
