How to implement system library function in real-time operating system

摘要

The present invention relates to a method for implementing a system library function required to increase the modularity and efficiency of software in developing a massive software in a large-capacity real-time exchange system.;(41 to 44) constituting a system library, a second step (51 to 55) for registering a system library when a system library registration request is received from a user after block loading, and a second step A third step 61 to 62 of calling the system library to the user after performing the steps 51 to 55 and a fourth step 71 to 76 of connecting to the actual required procedure after the third step 61 to 62, , And a fifth step (81 to 86) for guaranteeing a critical area when the system library is executed after performing the fourth step (71 to 76).
