LIBRARY
Pluggable Authentication Module Library (libpam, -lpam)
SYNOPSIS
#include
<sys/types.h>
#include <security/pam_appl.h>
#include
<security/openpam.h>
char *
openpam_readline(FILE
*f, int *lineno,
size_t *lenp);
DESCRIPTION
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, as is leading and trailing whitespace. Any amount
of linear whitespace is collapsed to a single space. 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
