Function Documentation

str2float()

enum str2int_errno str2float	(	float *	out,
		const char *	s
	)

Convert string s to float out. The format is the same as strtof, except that the following are inconvertible: NULL, empty string, leading whitespace, any trailing characters

Parameters

out	pointer to integer
s	string to convert

Returns

Indicates if the operation succeeded, or why it failed.

str2int()

enum str2int_errno str2int	(	int *	out,
		const char *	s
	)

Convert string s to int out. The format is the same as strtol, except that the following are inconvertible: NULL, empty string, leading whitespace, any trailing characters

Parameters

out	pointer to integer
s	string to convert

Returns

Indicates if the operation succeeded, or why it failed.

str2int64()

enum str2int_errno str2int64	(	int64_t *	out,
		const char *	s
	)

Convert string s to int64_t out. The format is the same as strtoll, except that the following are inconvertible: NULL, empty string, leading whitespace, any trailing characters

Parameters

out	pointer to integer
s	string to convert

Returns

Indicates if the operation succeeded, or why it failed.

str2uint()

enum str2int_errno str2uint	(	unsigned *	out,
		const char *	s
	)

Convert string s to unsigned out. The format is the same as strtoul, except that the following are inconvertible: NULL, empty string, leading whitespace, any trailing characters

Parameters

out	pointer to integer
s	string to convert

Returns

Indicates if the operation succeeded, or why it failed.
