PAM Library Functions pam_putenv(3PAM)
NAME
pam_putenv - change or add a value to the PAM environment
SYNOPSIS
cc [ flag ... ] file ... -lpam [ library ... ]
#include
int pam_putenv(pam_handle_t *pamh, const char *name_value);
DESCRIPTION
The pam_putenv() function sets the value of the PAM
environment variable name equal to value either by altering an existing PAM variable or by creating a new one.The name_value argument points to a string of the form
name=value. A call to pam_putenv() does not immediately
change the environment. All name_value pairs are stored in
the PAM handle pamh. An application such as login(1) maymake a call to pam_getenv(3PAM) or pam_getenvlist(3PAM) to
retrieve the PAM environment variables saved in the PAM han-
dle and set them in the environment if appropriate. login will not set PAM environment values which overwrite thevalues for SHELL, HOME, LOGNAME, MAIL, CDPATH, IFS, and
PATH. Nor will login set PAM environment values whichoverwrite any value that begins with LD_.
If name_value equals NAME=, then the value associated with
NAME in the PAM handle will be set to an empty value. If
name_value equals NAME, then the environment variable NAME
will be removed from the PAM handle.RETURN VALUES
The pam_putenv() function may return one of the following
values:PAM_SUCCESS The function returned successfully.
PAM_OPEN_ERR dlopen() failed when dynamically loading
a service module.PAM_SYMBOL_ERR Symbol not found.
PAM_SERVICE_ERR Error in service module.
