Function Documentation

open_ifstream()

std::ifstream open_ifstream ( const char * name, bool log, std::ios::openmode mode = std::ios::openmode() )

inline

Helper function to open an input file stream (= reading).

For compatibility with fopen() binary mode is always set. Use fs::OpenStream for more control.

Parameters

name	file name
log	if true, failure to open the file will be logged to errorstream
mode	additional mode bits (e.g. std::ios::ate)

Returns

file stream, will be !good in case of error

References fs::OpenStream().

open_ofstream()

std::ofstream open_ofstream ( const char * name, bool log, std::ios::openmode mode = std::ios::openmode() )

inline

Helper function to open an output file stream (= writing).

For compatibility with fopen() binary mode and truncate are always set. Use fs::OpenStream for more control.

Parameters

name	file name
log	if true, failure to open the file will be logged to errorstream
mode	additional mode bits (e.g. std::ios::app)

Returns

file stream, will be !good in case of error
