◆ cxxfclose()

int mutils::cxxfclose ( FILE * fp )

inline

Standardized fclose().

Equivalent to <cstdio> fclose(), except that the call is ignored if fp is stdin, stdout or stderr.

Parameters

[in] fp File stream pointer.

Definition at line 325 of file Log.h.

Referenced by mutils::Log::setStream().

◆ cxxfopen()

FILE* mutils::cxxfopen	(	const std::string &	file,
		const char *	mode
	)

inline

Standardized fopen().

Equivalent to <cstdio> fopen(), except:

the file name argument is a std::string
file names of "-" and "!" are interpreted as stdin/stdout and stderr, respectively.

Parameters

[in]	file	File name.
[in]	mode	File mode.

Definition at line 311 of file Log.h.

References std::string::c_str().

Referenced by mutils::Log::setStream().

◆ cxxfprintf()

template<typename... Args>

int mutils::cxxfprintf	(	FILE *	f,
		Args &&...	args
	)

inline

C fprintf() with type conversion (not safety).

Parameters

[in]	f	Open output file stream.
[in]	args	Input arguments (beginning with format string).

Returns: Number of bytes successfully written, or a negative value on error.

Warning: This method defeats all compile-time format checking (alas).

See also: mutils::cxxprintf, mutils::xfprintf

Definition at line 284 of file Log.h.

References Cform().

Referenced by mutils::Log::message().

◆ cxxprintf()

template<typename... Args>

int mutils::cxxprintf ( Args &&... args )

inline

C printf() with type conversion (not safety).

Wraps each argument in a Cform() call and passes them to printf(). This converts all signed integers to type long and all unsigned integers to type unsigned long, so that the format conversion applied to them must be %ld or %lu, respectively. Characters are converted to type int and hence should use either %c or %d. Both C-strings and C++ std::string can be given as arguments using the %s conversion. All the usual format qualifiers may also be used.

Parameters

[in] args Input arguments (beginning with format string).

Returns: Number of bytes successfully written, or a negative value on error.

Warning: This method defeats all compile-time format checking (alas).

See also: mutils::xprintf

Definition at line 273 of file Log.h.

References Cform().

◆ cxxsnprintf()

template<typename... Args>

int mutils::cxxsnprintf	(	char *	buf,
		size_t	len,
		Args &&...	args
	)

inline

C snprintf() with type conversion (not safety).

Parameters

[in]	buf	Output buffer.
[in]	len	Buffer length.
[in]	args	Input arguments (beginning with format string).

Returns: Minimum required buffer size minus one, or a negative value on error.

Warning: This method defeats all compile-time format checking (alas).

◆ exitException()

void mutils::exitException	(	std::exception &	ex,
		int	status = `EXIT_FAILURE`
	)

inline

Exits program with exception message. Exits the program (with status) after displaying the exception ex.

Note: This method does not return.

Parameters

[in]	ex	Input exception.
[in]	status	Exit status.
