Detailed Description

Extracts values from libmagic constant pairs.

LibmagicPairConverter wraps a LibmagicPairT (pair of int constant and const char* name) and provides implicit conversions to either the integer value or string name.

Usage Example

// Extract integer constant for libmagic API call
LibmagicValueT magic_mime = LibmagicPairConverter(LIBMAGIC_FLAGS[4]);
 
// Extract string name for ToString/logging
LibmagicValueNameT name = LibmagicPairConverter(LIBMAGIC_FLAGS[4]);
// name == "MimeType"
