# getline/getdelim for RT-Thread POSIX(IEEE Std 1003.1-2008)

|

[](https://travis-ci.org/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.
|
||||

||||
