PAM_MISC_SETENV(3)						 Linux-PAM Manual						PAM_MISC_SETENV(3)

NAME
       pam_misc_setenv - BSD like PAM environment variable setting

SYNOPSIS
       #include <security/pam_misc.h>

       int pam_misc_setenv(pam_handle_t *pamh, const char *name, const char *value, intreadonly);

DESCRIPTION
       This function performs a task equivalent to pam_putenv(3), its syntax is, however, more like the BSD style function; setenv(). The name and
       value are concatenated with an '=' to form a name=value and passed to pam_putenv(). If, however, the PAM variable is already set, the
       replacement will only be applied if the last argument, readonly, is zero.

SEE ALSO
       pam_putenv(3), pam(8)

STANDARDS
       The pam_misc_setenv function is part of the libpam_misc Library and not defined in any standard.
