This series is modeled on v1.4.1. In this version, memory allocation is divided into two types: normal and memory pool. This article introduces general memory allocation, all functions in the file mem. C (this summary introduces the L496-L518 ). 1.

The final result of two or more processes reading and writing shared data depends on the exact sequence of processes running. This is easy to happen when resources are shared. The solution is to set up a critical zone to allow processes to access
