L_LTFIL_API L_SSIZE_T L_GetIgnoreFilters(pszFilters, uSize);
Retrieves the current ignored filters list that LEADTOOLS should never load, even if present.
Pointer to a character string to be updated with the current ignored filters list.
The size in bytes of the buffer pointed to by pszFilters
.
Value | Meaning |
---|---|
>=0 | The size in bytes of the ignored filters list. |
In case the current ignored filters list should be changed, call this function before calling the L_IgnoreFilters function.
To retrieve the ignored filters list, the user should do the following:
pszFilters
as NULL and uSize
as 0 to retrieve the size required for the filters list as returned value.Required DLLs and Libraries
Win32, x64, Linux.
