CFStringGetCString
CFStringGetCString is a function in the Core Foundation framework of macOS and iOS, used to convert a CFString (Core Foundation string) to a C string (null-terminated array of characters). This function is particularly useful when interfacing with C-based APIs that require null-terminated strings.
The function prototype is as follows:
Boolean CFStringGetCString(CFStringRef theString, char *buffer, CFIndex bufferSize, CFStringEncoding encoding);
Here's a brief explanation of the parameters:
- CFStringRef theString: The CFString to be converted.
- char *buffer: A pointer to a buffer where the C string will be stored.
- CFIndex bufferSize: The size of the buffer, including space for the null terminator.
- CFStringEncoding encoding: The encoding to use for the conversion.
The function returns a Boolean value indicating whether the conversion was successful. If the buffer is too
It's important to note that CFStringGetCString does not allocate memory for the buffer. The caller is responsible
CFStringGetCString is a low-level function and should be used with caution. It's recommended to use higher-level
