PAM_STRERROR(3) Linux-PAM Manual PAM_STRERROR(3)NAME
pam_strerror - return string describing PAM error code
const char *pam_strerror(pam_handle_t *pamh, int errnum);
The pam_strerror function returns a pointer to a string describing the error code passed in the argument errnum, possibly using the
LC_MESSAGES part of the current locale to select the appropriate language. This string must not be modified by the application. No library
function will modify this string.
This function returns always a pointer to a string.

pam_putenv - set or change PAM environment variable
int pam_putenv(pam_handle_t *pamh, const char *name_value);
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.
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
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.
Argument name_value given is a NULL pointer.
Variable requested (for deletion) is not currently set.
The pamh handle is corrupt.
Memory buffer error.
The environment variable was successfully updated.
