Note This function is provided only for compatibility with 16-bit applications written for Windows. Applications should store initialization information in the registry. Syntax C++ DWORD WINAPI GetPrivateProfileSection( __in LPCTSTR lpAppName, __out LPTSTR lpReturnedString, __in DWORD nSize, __in LPCTSTR lpFileName ); Parameters lpAppName [in] The name of the section in the initialization file. lpReturnedString [out] A pointer to a buffer that receives the key name and value pairs associated with the named section. The buffer is filled with one or more null-terminated strings; the last string is followed by a second null character. nSize [in] The size of the buffer pointed to by the lpReturnedString parameter, in characters. The maximum profile section size is 32,767 characters. lpFileName [in] The name of the initialization file. If this parameter does not contain a full path to the file, the system searches for the file in the Windows directory. Return Value The return value specifies the number of characters copied to the buffer, not including the terminating null character. If the buffer is not large enough to contain all the key name and value pairs associated with the named section, the return value is equal to nSize minus two. Remarks The data in the buffer pointed to by the lpReturnedString parameter consists of one or more null-terminated strings, followed by a final null character. Each string has the following format: key=string The GetPrivateProfileSection function is not case-sensitive; the string pointed to by the lpAppName parameter can be a combination of uppercase and lowercase letters. This operation is atomic; no updates to the specified initialization file are allowed while the key name and value pairs for the section are being copied to the buffer pointed to by the lpReturnedString parameter. The system maps most .ini file references to the registry, using the mapping defined under the following registry key: HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\IniFileMapping This mapping is likely if an application modifies system-component initialization files, such as Control.ini, System.ini, and Winfile.ini. In these cases, the 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 profile functions use the following steps to locate initialization information: Look in the registry for the name of the initialization file under the IniFileMapping key. Look for the section name specified by lpAppName. This will be a named value under the key that has the name of the initialization file, or a subkey with this name, or the name will not exist as either a value or subkey. If the section name specified by lpAppName is a named value, then that value specifies where in the registry you will find the keys for the section. If the section name specified by lpAppName is a subkey, then named values under that subkey specify where in the registry you will find the keys for the section. If the key you are looking for does not exist as a named value, then there will be an unnamed value (shown as If the section name specified by lpAppName does not exist as a named value or as a subkey, then there will be an unnamed value (shown as If there is no subkey or entry for the section name, then look for the actual initialization file on the disk and read its contents. 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. Comments (any line that starts with a semicolon) are stripped out and not returned in the lpReturnedString buffer.
