pam_misc_setenv - BSD like PAM environment variable setting

  #include <security/pam_misc.h>

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

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.

*pam_putenv*(3), *pam*(8)

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