* GMT HASH STRUCTURE DEFINITION
*--------------------------------------------------------------------*/
/* To avoid lots of dynamic memory allocation for the hash lookup tables we
* use a statically allocated structure. By determining that the max number
* of identical hash numbers across all the keywords is 16, we simply allocate
* space for 16 entries for each structure. Should later additions to GMT's
* default parameters, colornames, etc increase this value we will be warned
* and can change the entry GMT_HASH_MAXDEPTH below accordingly.
*/
#define GMT_HASH_MAXDEPTH 16
/*! Used to relate text keywords to array indices */
struct GMT_HASH {
unsigned int id[GMT_HASH_MAXDEPTH]; /* Indices of corresponding keyword with identical hash value */
unsigned int n_id; /* Number of hash entries for this item */
char *key[GMT_HASH_MAXDEPTH]; /* Name of these entries */
};
