OPENPAM_READLINE(3) BSD Library Functions Manual OPENPAM_READLINE(3)NAMEopenpam_readline — read a line from a file
Pluggable Authentication Module Library (libpam, -lpam)
openpam_readline(FILE *f, int *lineno, size_t *lenp);
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
The openpam_readline function returns NULL on failure.
