pam_putenv(3PAM)					       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 <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.

NOTES

       The interfaces in  libpam are MT-Safe only if each thread within the multithreaded application uses its own PAM handle.

PAM_PUTENV(3)                                                    Linux-PAM Manual                                                    PAM_PUTENV(3)

NAME

       pam_putenv - set or change PAM environment variable

SYNOPSIS

       #include <security/pam_appl.h>

       int pam_putenv(pam_handle_t *pamh, const char *name_value);

DESCRIPTION

       The pam_putenv function is used to add or change the value of PAM environment variables as associated with the pamh handle.

       The pamh argument is an authentication handle obtained by a prior call to pam_start(). The name_value argument is a single NUL terminated
       string of one of the following forms:

       NAME=value of variable
           In this case the environment variable of the given NAME is set to the indicated value: value of variable. If this variable is already
           known, it is overwritten. Otherwise it is added to the PAM environment.

       NAME=
           This function sets the variable to an empty value. It is listed separately to indicate that this is the correct way to achieve such a
           setting.

       NAME
           Without an '=' the pam_putenv() function will delete the corresponding variable from the PAM environment.

       pam_putenv() operates on a copy of name_value, which means in contrast to putenv(3), the application is responsible to free the data.

RETURN VALUES

       PAM_PERM_DENIED
           Argument name_value given is a NULL pointer.

       PAM_BAD_ITEM
           Variable requested (for deletion) is not currently set.

       PAM_ABORT
           The pamh handle is corrupt.

       PAM_BUF_ERR
           Memory buffer error.

       PAM_SUCCESS
           The environment variable was successfully updated.
