I don't believe it does. It should be fairly simple for you to implement 
that function on top of PR_Read.

One of the reasons for this not being included in NSPR may be that the 
EOL characters are platform-specific.

Having done a lot of server programming with NSPR, I can also say that I 
would not use a generic function to perform this task - each protocol 
RFC is different and allows a certain number of newlines, spaces, etc. 
You are better off using the binary PR_Read or PR_Recv functions, and 
doing exactly what you want on top of it.
