  openpam_readline(FILE
    *f, int *lineno,
    size_t *lenp);
openpam_readlinev() function may be used to achieve
  similar results.The openpam_readline() function reads a
    line from a file, and returns it in a NUL-terminated buffer allocated with
    malloc(3).
The openpam_readline() function performs a
    certain amount of processing on the data it reads:
If lineno is not
    NULL, the integer variable it points to is
    incremented every time a newline character is read.
If lenp is not NULL,
    the length of the line (not including the terminating NUL character) is
    stored in the variable it points to.
The caller is responsible for releasing the returned buffer by passing it to free(3).
openpam_readline() function returns
  NULL on failure.
openpam_readline() function is an OpenPAM extension.
openpam_readline() function and this manual page
  were developed for the FreeBSD Project by ThinkSec AS
  and Network Associates Laboratories, the Security Research Division of Network
  Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035
  (“CBOSS”), as part of the DARPA CHATS research program.
The OpenPAM library is maintained by Dag-Erling Smørgrav <des@des.no>.
