SynopsisStructure used to store all possible data types. Prototype
#include "uemf.h"
typedef struct {
union {
char bool;
char byteint;
short shortint;
char percent;
long integer;
long hex;
long octal;
long big[2];
double floating;
char_t *string;
char *bytes;
char_t *errmsg;
void *symbol;
} value;
value_type_t type;
unsigned int valid;
unsigned int allocated; /* String was balloced */
} value_t;
typedef enum {
undefined = 0,
byteint = 1,
shortint = 2,
integer = 3,
hex = 4,
percent = 5,
octal = 6,
big = 7,
bool = 8,
floating = 9,
string = 10,
bytes = 11,
symbol = 12,
errmsg = 13
} value_type_t;
DescriptionThe value_t type is used heavily in the GoAhead EMF database API. Example
/********************************************/
/*
* Initialize a boolean value.
*/
value_t valueBool(int value)
{
value_t v = VALUE_VALID;
v.type = bool;
v.value.bool = (char) value;
return v;
}
