Getuid function

[Krishnan Viswanathan]

I am writing a small c code.
Is there a function which gives the username directly instead of uid ?

Thanks

Hi:

You can use the getlogin function, although the proper procedure is to call getlogin(); if that returns a NULL then you should call getpwuid(getuid()) to return a pointer to a passwd struct.

Man 3 getlogin, getpwuid for details.
