copied!<p>The boolean is "never" a separate value in C. So a struct might be in order to get you going.</p> <p>It is true that you do not initialize the mem area so you need to do that individually.</p> <p>Here is a simple example of how you could do it with unions structs and enums</p> <pre><code>typedef unsigned char BYTE; typedef unsigned short WORD; typedef unsigned long int DWORD; typedef unsigned long long int DDWORD; enum STATUS { status0 = 0x01, status1 = 0x02, status2 = 0x04, status3 = 0x08, status4 = 0x10, status5 = 0x20, status6 = 0x40, status7 = 0x80, status_group = status0 + status1 +status4 }; #define GET_STATUS( S ) ( ((status.DDBuf&(DDWORD)S)==(DDWORD)S) ? 1 : 0 ) #define SET_STATUS( S ) ( (status.DDBuf|= (DDWORD)S) ) #define CLR_STATUS( S ) ( (status.DDBuf&= ~(DDWORD)S) ) static union { BYTE BBuf[8]; WORD WWBuf[4]; DWORD DWBuf[2]; DDWORD DDBuf; }status; int main(void) { // Reset status bits status.BBuf[0] = 0; printf( "%d \n", GET_STATUS( status0 ) ); SET_STATUS( status0 ); printf( "%d \n", GET_STATUS( status0 ) ); CLR_STATUS(status0); printf( "%d \n", GET_STATUS( status0 ) ); SET_STATUS( status_group ); printf( "%d \n", GET_STATUS( status0 ) ); system( "pause" ); return 0; } </code></pre> <p>Hope this helps. This example can handle up until 64 status booleans and could be easy extended.</p> <p>This exapmle is based on Char = 8 bits int = 16 bits long int = 32 bits and long long int = 64 bits</p> <p>I have now also added support for status groups.</p>
