Function Documentation

int se_icompare	(	const char *	a,
		const char *	b
	)

Compares a with b, regardless of case.

Parameters:

	a	The string to compare b with.
	b	The string to compare a with.

Returns:

Zero if the strings are equal. Else less than zero is returned if a is less than b. Otherwise positive value is returned if a is greater than b.

int se_incompare	(	const char *	a,
		const char *	b,
		const size_t	n
	)

Compares a with b, regardless of case for n characters.

Parameters:

	a	The string to compare b with.
	b	The string to compare a with.
	n	The maximum number of characters to compare.

Returns:

Zero if the strings are equal. Else less than zero is returned if a is less than b. Otherwise positive value is returned if a is greater than b.

bool se_is_space

(

const char

ch

)

Returns true if the given character is a tab or space.

Parameters:

ch

The char to test.

Returns:

true if the character is or ' '. False is returned otherwise.

char* se_nchr	(	char *	buffer,
		const size_t	n,
		const char	ch
	)

Returns the first occurance of the given character for a max of n characters.

Parameters:

	buffer	The string to search in.
	ch	The char to search for.
	n	The maximum number of characters to traverse.

Returns:

The first occurance of ch. On error, NULL is returned.

void se_remove_trailing_spaces

(

char *

buffer

)

Removes spaces from buffer by replacing the first trailing space with a NULL terminator.

See also:

se_skip_leading_spaces()

Parameters:

buffer

The NULL terminated string to remove spaces from.

char* se_skip_leading_spaces

(

char *

buffer

)

Returns a new pointer from buffer past the leading spaces.

Note: Be careful with malloc()'d memory since the pointer will be lost unless you save it. A space is anything given by isspace(ch).

See also:

se_remove_trailing_spaces()

Parameters:

buffer

The NULL terminated string to skip spaces from.

Returns:

A pointer to the first non-space character of buffer.

bool se_to_float	(	const char *	buffer,
		float *	dest
	)

Attempts to parse the string in buffer as a floating point.

Parameters:

	buffer	The string to parse.
	dest	Where to put the float. Only written to on success.

Returns:

true if the float was parsed. Otherwise, false is returned on error.

bool se_to_ulint	(	const char *	buffer,
		unsigned long int *	dest
	)

Attempts to parse the string in buffer as an unsigned long int in base-10.

Parameters:

	buffer	The string to parse.
	dest	Where to put the unsigned long integer. Only written to on success.

Returns:

true if the integer was parsed. Otherwise, false is returned on error.

char* se_trim_spaces

(

char *

buffer

)

Trims leading and trailing spaces from a string.

See also:

se_remove_trailing_spaces()

se_skip_leading_spaces()

Parameters:

buffer

The NULL terminated string to trim spaces from.

Returns:

A pointer to the first non-space character of buffer.
