SYNOPSIS

STRUCTS_ID_TYPE(idlist, vsize);

DESCRIPTION

The data structure represented is an integral value that may take one of a fixed set of values. The possible values are defined by the idlist argument, which is a pointer to an array of struct structs_id:

struct structs_id {
    const char  *id;        /* string representation */
    u_int32_t   value;      /* integer representation */
    u_int       imatch;     /* case-insensitive matching allowed */
};

The id points to a unique string representing the value; imatch, determines whether the parsing of the ASCII representation is case-insensitive. value is the actual integer value. The first element in the array used as the default value. The array is terminated with an entry having id equal to NULL.

vsize is the size of the integral type used to store the value, which must be 1, 2, or 4.
