pam_getenv(3PAM)					       PAM Library Functions						  pam_getenv(3PAM)

NAME

       pam_getenv - returns the value for a PAM environment name

SYNOPSIS

       cc [ flag ... ] file ... -lpam [ library ... ]
       #include <security/pam_appl.h>

       char *pam_getenv(pam_handle_t *pamh, const char *name);

DESCRIPTION

       The  pam_getenv()  function searches the PAM handle pamh for a value associated with name. If a value is present, pam_getenv() makes a copy
       of the value and returns a pointer to the copy back to the calling application. If no such entry exists, pam_getenv() returns  NULL. It	is
       the responsibility of the calling application to free the memory returned by pam_getenv().

RETURN VALUES

       If successful, pam_getenv() returns a copy of the value associated with name in the PAM handle;
	otherwise, it returns a  NULL pointer.

NAME

       pam_putenv - change or add a value to the PAM environment

SYNOPSIS

       cc [ flag ... ] file ... -lpam [ library ... ]
       #include <security/pam_appl.h>

       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) may make a call to  pam_getenv(3PAM) or pam_geten-
       vlist(3PAM) to retrieve the PAM environment variables saved in the PAM handle and set them in the environment if  appropriate.  login  will
       not  set  PAM environment values which overwrite the values for	SHELL, HOME, LOGNAME, MAIL, CDPATH, IFS, and  PATH. Nor will login set PAM
       environment values which overwrite 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.

       PAM_SYSTEM_ERR	       System error.

       PAM_BUF_ERR	       Memory buffer error.

       PAM_CONV_ERR	       Conversation failure.

       PAM_PERM_DENIED	       Permission denied.
