Function Documentation

PMPAPI uint32_t pmplib_interlocked_decrement ( uint32_t *  count  ) 

Decrement a variable value and check the resultant value.

This function prevents more than one thread from using pmplib_interlocked_increment() or pmplib_interlocked_decrement() function to access the same variable simultaneously.

Parameters:
count The pointer to the variable whose value is to be decreased.
Return values:
uint32_t The value of the variable after this decrement.

PMPAPI uint32_t pmplib_interlocked_increment ( uint32_t *  count  ) 

Increment a variable value and check the resultant value.

This function prevents more than one thread from using pmplib_interlocked_increment() or pmplib_interlocked_decrement() function to access the same variable simultaneously.

Parameters:
count The pointer to the variable whose value is to be increased.
Return values:
uint32_t The value of the variable after this increment.
