.IR "lc_var_type_t type"
.RS
The
.IR type
parameter indicates the type of values that are acceptable for this callback.  Currently only LC_VAR_NONE is acceptable, since callbacks may not have values (though they may have arguments).
parameter indicates the type of values that are acceptable for this callback.  A value of LC_VAR_NONE means that the command will accept no arguments, while a value of LC_VAR_UNKNOWN indicates that it's not known whether or not an argument is applicable, this will also disable command line processing.  Any other value is currently ignored.

The
.IR callback

.TP
LC_VAR_SIZE_INT
For a "int" integer type that can have size modifiers, such as 'G' or gigabytes, 'M' for megabytes, 'K' for kilobytes.  The data passed should be of type "int *".
.TP
LC_VAR_SIZE_SHORT
For a "short" integer type that can have size modifiers, such as 'G' or gigabytes, 'M' for megabytes, 'K' for kilobytes.  The data passed should be of type "short *".
.TP
LC_VAR_SIZE_SIZE_T
For a "size_t" data type that can have size modifiers, such as 'G' or gigabytes, 'M' for megabytes, 'K' for kilobytes.  The data passed should be of type "size_t *".
.TP
LC_VAR_TIME
Not implemented.
.TP
LC_VAR_DATE
Not implemented.
.TP
LC_VAR_BOOL_BY_EXISTANCE
This type of variable takes no arguments, it is set to true (1) by its existance in a configuration file, environment variable, or on the command line.  If it is not specified, the value of the data passed is not changed.  The data passed should be of type "int *".

.SH "RETURN VALUE"
On success 0 is returned, otherwise -1 is returned.
