-
-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].
