Performance optimization methods and ideas for large C projects. Performance optimization strategies for x86 projects that encounter performance bottlenecks when porting to low performance processors.

GDB is a powerful program debugging tool based on command line under UNIX/LINUX operating system released by GNU Source Organization. For a C/C ++ programmer working on Linux, GDB is an essential tool.

Reduce page tables by increasing the size of operating system pages to avoid fast table misses. Large page memory optimizer is designed for malloc mechanism, which means allocating large pages to increase TLB hit ratio.

In development, we just need to know that lib is needed at compile time and DLL is needed at run time. If you want to compile source code, lib is all you need. If you want dynamically connected programs to run, you need only a DLL. This article will more clearly understand the difference, generation, use of the two.

Read the binary file (any file will do; this article uses binary as an example) and read the entire contents of the binary file into a char* string. With fseek() and fread() functions to achieve file reading advanced methods.

SQLCipher is based on SQLite, and thus, the majority of the accessible API is identical to the C/C++ interface for SQLite 3. However, SQLCipher does add a number of security specific extensions in the form of PRAGMAs, SQL Functions and C Functions.

In computer programming, create, read, update, and delete (CRUD) are the four basic functions of persistent storage. Alternate words are sometimes used when defining the four basic functions of CRUD, such as retrieve instead of read, modify instead of update, or destroy instead of delete. CRUD is also sometimes used to describe user interface conventions that facilitate viewing, searching, and changing information, often using computer-based forms and reports.

Makefiles define a set of rules that specify which files need to be compiled first, which files need to be compiled later, which files need to be recompiled, and even more complex functional operations, because makefiles are like Shell scripts that also execute operating system commands. One of the benefits of Makefiles is that they are “automatically compiled”. The entire project is automatically compiled, greatly improving the efficiency of software development.
