pText |
Pointer to the buffer to be updated with the item's character string. |
puLen |
Pointer to variable to be updated with the length of the item's current character string. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
To use this function:
1. |
Call this function passing pText as NULL to obtain the text length in the puLen parameter. |
2. |
Allocate a buffer of size (*puLen + 1). |
3. |
Call this function with passing the allocated buffer to the pText parameter to obtain the text. |
Use L_AnnSetAutoText to modify the automated menu item.
Before calling this function, you must declare a variable as a pointer to a character string. Then, pass the variable in the pText parameter. This function will update the variable with the automation item's character string.
