OPENPAM_READLINE(3)     NetBSD Library Functions Manual    OPENPAM_READLINE(3)


NAME
openpam_readline -- read a line from a file
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 terminat- ing 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
free(3), malloc(3), pam(3)
STANDARDS
The openpam_readline function is an OpenPAM extension.
