Definition
Noun: A library routine is a pre-written, tested, and debugged subroutine or function that is stored in a program library. It is a reusable piece of code designed to perform a specific, common task, which can be called by different software programs to avoid the need for programmers to write the same code repeatedly.
Usage
A library routine is a fundamental component in software development, promoting code reuse, efficiency, and reliability. Programmers include or link to these routines from a library to add standard functionality to their programs.
Examples
- The programmer used a library routine to handle complex mathematical calculations, saving development time.
- Standard input/output operations are often performed by calling a library routine.
- Debugging is easier when you rely on well-tested library routines for common tasks.
Advanced Usage
- Dynamic Linking: A library routine can be linked to a program at runtime, reducing the initial program size.
- Static Library: A collection of library routines that are copied and embedded into the final executable program during compilation.
Variants and Related Words
- Subroutine: A sequence of program instructions that performs a specific task.
- Function: A subroutine that returns a value.
- Procedure: A subroutine, similar to a function but may not return a value.
- API (Application Programming Interface): A set of defined library routines, protocols, and tools for building software.
Synonyms
- Built-in function
- Standard function
- Predefined routine
Related Phrases
- Call a library routine: To invoke or execute a routine from a library within a program.
- The application calls a library routine to sort the data.
- Link against a library: To connect a program to a library so it can use the library routines.
- You must link against the math library to use those trigonometric functions.
Noun
- a debugged routine that is maintained in a program library
