OPENPAM_READLINE(3)        Library Functions Manual        OPENPAM_READLINE(3)

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.

SEE ALSO
     openpam_readlinev(3), openpam_readword(3), pam(3)

STANDARDS
     The openpam_readline() function is an OpenPAM extension.
