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. SEE ALSO
