◆ file_get_contents()

std::string mrpt::io::file_get_contents ( const std::string &  fileName)

Loads an entire text file and return its contents as a single std::string.

Exceptions
std::runtime_errorOn any read error.
See also
loadBinaryFile(), loadTextFile()
Note
Relying on C++17 RVO to return a string without worring on return-by-value of big objects.
