void Show_Metafile | ( | char * | options | ) |
Returns a list of the metafile attributes that have been set on the currently open segment.
options | - A list of the current metafile attributes. Passed by reference. Returned to user. |
When the value being passed back is a string, be sure you've declared your string variable to be long enough.
In C, "passed by reference" means that you have to allocate an appropriate variable, either statically or off the stack, and pass a pointer to that variable to the HOOPS routine. To generate a pointer to a variable C, you prefix the variable with a "&". In other languages you normally don't have to do anything different from usual.
The Show_Metafile() routines will complain if they're called and the attribute is not actually set in the segment. Use Show_Existence() to avoid this, if necessary.
void Show_Net_Metafile | ( | char * | options | ) |
Similar to Show_Metafile(), but returns the net effective settings rather than the local ones.
options | - A list of the current metafile attributes. Passed by reference. Returned to user. |
void PShow_Net_Metafile | ( | int | keycount, | |
HC_KEY * | pathkeys, | |||
char * | options | |||
) |
Similar to Show_Net_Metafile(), but returns the net effective settings along a discrete segment path.
keycount | The size of pathkeys | |
pathkeys | An array of HC_KEY's delineating a path of segments. | |
options | A list of the current metafile attributes. Passed by reference. Returned to user. |
By default, HOOPS will determine the Net attribute from the last specified key all the way to the root. If you add -1 at the end of the array, the PShow_Net routines will not proceed beyond the end of the last specified key.

void Show_One_Metafile | ( | const char * | type, | |
char * | value | |||
) |
Similar to Show_Metafile() but returns a single setting, rather than the entire set.
type | The type in type = value. | |
value | The value of type. Passed by reference. Returned to user. |
void Show_One_Net_Metafile | ( | const char * | type, | |
char * | value | |||
) |
Similar to Show_One_Metafile() but returns the net effective setting rather than the local one.
type | The type in type = value. | |
value | The value of type. Passed by reference. Returned to user. |
void PShow_One_Net_Metafile | ( | int | count, | |
HC_KEY * | keys, | |||
const char * | type, | |||
char * | value | |||
) |
Similar to Show_One_Net_Metafile() but returns the net settings along a discrete path.
count | The size of keys | |
keys | An array of HC_KEY's delineating a path of segments. | |
type | The type in type = value. | |
value | The value of type. Passed by reference. Returned to user. |
