NAME
openpam_readline —
read a line from a
file
SYNOPSIS
#include <sys/types.h>
#include <stdio.h>
#include <security/pam_appl.h>
#include <security/openpam.h>
char *
openpam_readline(
FILE
*f,
int *lineno,
size_t *lenp);
DESCRIPTION
This function is
deprecated and may be removed in a future release without further warning. The
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:
- Comments (introduced by a hash sign) are stripped.
- Blank lines are ignored.
- If a line ends in a backslash, the backslash is stripped
and the next line is appended.
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).
RETURN VALUES
The
openpam_readline() function returns
NULL
on failure.

STANDARDS

openpam_readline() function is an OpenPAM extension.
