DESCRIPTION
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
