PAM_MISC_DROP_ENV(3) Linux-PAM Manual PAM_MISC_DROP_ENV(3)NAME
pam_misc_drop_env - liberating a locally saved environment
int pam_misc_drop_env(char **env);
This function is defined to complement the pam_getenvlist(3) function. It liberates the memory associated with env, overwriting with 0 all
memory before free()ing it.
SEE ALSO pam_getenvlist(3), pam(8)STANDARDS
The pam_misc_drop_env function is part of the libpam_misc Library and not defined in any standard.

pam_getenvlist - getting the PAM environment
char **pam_getenvlist(pam_handle_t *pamh);
The pam_getenvlist function returns a complete copy of the PAM environment as associated with the handle pamh. The PAM environment
variables represent the contents of the regular environment variables of the authenticated user when service is granted.
The format of the memory is a malloc()'d array of char pointers, the last element of which is set to NULL. Each of the non-NULL entries in
this array point to a NUL terminated and malloc()'d char string of the form: "name=value".
It should be noted that this memory will never be free()'d by libpam. Once obtained by a call to pam_getenvlist, it is the responsibility
of the calling application to free() this memory.
It is by design, and not a coincidence, that the format and contents of the returned array matches that required for the third argument of
the execle(3) function call.
The pam_getenvlist function returns NULL on failure.
