    Command:

    pam_putenv

    
    
    

    SYNOPSIS

           #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.
    
           pam_putenv() operates on a copy of name_value, which means in contrast
           to putenv(3), the application is responsible to free the data.
    
    
    

    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.
