Functions
void	file_converter_emit_bytes (std::ostream &out, const std::string &s)
	Emit the bytes of s to out as comma-separated decimal byte values (not character literals).
void	file_converter_append (std::istream &in, std::ostream &out, bool line_marker, const std::string &file_name)
	Append the contents of in to out as the body of a C character-array initialiser; the enclosing braces and trailing null terminator are supplied by the caller.

Function Documentation

file_converter_append()

void file_converter_append ( std::istream & in, std::ostream & out, bool line_marker, const std::string & file_name )

inline

Append the contents of in to out as the body of a C character-array initialiser; the enclosing braces and trailing null terminator are supplied by the caller.

Each input line contributes its bytes followed by a newline byte (the sole character literal emitted) and a physical line break, so one output line corresponds to one input line – this keeps the generated initialiser diffable and within compiler line-length limits. When line_marker is set, a #line directive naming file_name is emitted first so that diagnostics refer to the original file.

file_converter_emit_bytes()

void file_converter_emit_bytes ( std::ostream & out, const std::string & s )

inline

Emit the bytes of s to out as comma-separated decimal byte values (not character literals).

A byte with the high bit set is written with a (char) cast so the surrounding braced initialiser is valid regardless of whether char is signed or unsigned – a brace initialiser would otherwise reject the narrowing conversion of a value > 127.
