# getline/getdelim for RT-Thread POSIX
[
![Build Status
](
https://travis-ci.org/ivanrad/getline.svg?branch=master
)

https://github.com/ivanrad/getline
Read a delimited record from stream.
Yet another (hopefully portable C) implementation of getline/getdelim.
These are ersatz functions, a drop-in replacement, to be used on those occasions when your C library does not already support them.
For more details, see
[
Open Group Base Specification for getdelim/getline
][
opengroup-spec
]
.
## Building the project
Just run
`make`
.
