NAME
pam_putenv - set or change PAM environment variableSYNOPSIS
#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.
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.
