Function Documentation

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_error

On any read error.

loadBinaryFile(), loadTextFile()

Note

Relying on C++17 RVO to return a string without worring on return-by-value of big objects.
