The GetProfileInt function retrieves an integer from the specified key name in the given section of the WIN.INI file. This function is provided for compatibility with 16-bit Windows-based applications. Win32-based applications should store initialization information in the registry.
UINT GetProfileInt(
LPCTSTR lpAppName, |
// address of section name |
LPCTSTR lpKeyName, |
// address of key name |
INT nDefault |
// default value if key name is not found |
); |
The return value is the integer equivalent of the string following the key name in WIN.INI. If the function cannot find the key, the return value is the default value. If the value of the key is less than zero, the return value is zero.
If the key name consists of digits followed by characters that are not numeric, the function returns only the value of the digits. For example, the function returns 102 for the following line: KeyName=102abc.
HKEY_LOCAL_MACHINE\Software\Microsoft\
Windows NT\CurrentVersion\IniFileMapping
When the operation has been mapped, the GetProfileInt function retrieves information from the registry, not from the initialization file; the change in the storage location has no effect on the function’s behavior.
The Win32 Profile functions (Get/WriteProfile*, Get/WritePrivateProfile*) use the following steps to locate initialization information:
HKEY_LOCAL_MACHINE\Software\Microsoft\
Windows NT\CurrentVersion\IniFileMapping\myfile.ini
When looking at values in the registry that specify other registry locations, there are several prefixes that change the behavior of the ini file mapping:
! - this character forces all writes to go both to the registry and to the .INI file on disk.
# - this character causes the registry value to be set to the value in the Windows 3.1 .INI file when a new user logs in for the first time after setup.
@ - this character prevents any reads from going to the .INI file on disk if the requested data is not found in the registry.
USR: - this prefix stands for HKEY_CURRENT_USER, and the text after the prefix is relative to that key.
SYS: - this prefix stands for HKEY_LOCAL_MACHINE\SOFTWARE, and the text after the prefix is relative to that key.
