What are the differences between system calls and library calls?
An example of an AI chatbot conversation about system calls vs library calls.
What are the differences between system calls and library calls?
System calls are requests to the operating system for services, while library calls are functions provided by programming libraries.
Can you give me an example of each?
Sure! An example of a system call is open() to open a file, while a library call could be printf() from the C standard library.
Why would I use a library call instead of a system call?
Library calls often provide higher-level abstractions, making them easier to use and more portable across different systems.
Are there performance differences between the two?
Yes, system calls can be slower due to context switching between user mode and kernel mode, while library calls are generally faster.
