When creating a folder, you must pass in a reference to a UCHAR to get the folder

number back from the function. The following example shows how to create and delete a

folder:

UCHAR temp;

if(IMU_MCS_SUCCESS != BMCSCreateFolder((CP_CHAR *)"test", &temp))

{

// error handling…

}

if(IMU_MCS_SUCCESS != BMCSDeleteFolder((CP_CHAR*)"test"))

{

// error handling…

}

Changing a Variable’s Name and Attributes

The MCS BIOS provides several functions to control different aspects of a variable. This

includes renaming a variable, copying and moving a variable, setting variable attributes

and searching for variables.

To rename a variable the following function is used:

int BMCSRenameVariable(CP_CHAR *pcpcFolderName,

CP_CHAR *pcpcOldValName, CP_CHAR *pcpcNewValName)

Variables also support being locked, meaning that their value cannot be altered. To lock

or unlock a variable you can use the following functions:

int BMCSVariableLockOn(CP_CHAR *pcpcFolderName, CP_CHAR *pcpcValName)

int BMCSVariableLockOff(CP_CHAR *pcpcFolderName, CP_CHAR *pcpcValName)

There are also functions to check the attributes of a variable. A variable can have the

following possible attributes:

IMU_MCS_FlagLock Folder/Variable Lock Flag

IMU_MCS_FlagUsing Folder/Variable In Use Flag

IMU_MCS_FlagUsed Folder/Variable Used Flag

IMU_MCS_FlagCursor Cursor on

IMU_MCS_FlagSelect Select on

To get or set a variable’s attributes, use the following functions:

int BMCSSetVariableAttribute (CP_CHAR *pcpcFolderName,

CP_CHAR *pcpcValName, UCHAR ucAttributeData)

int BMCSGetVariableAttribute (CP_CHAR *pcpcFolderName,

CP_CHAR *pcpcValName, UCHAR *pucAttributeData)

Here is an example that uses some of these functions:
