Function Documentation

int EatWhitespace

(

const char **

StrPtr

)

Eat whitespace characters in a string.

Parameters

StrPtr

char** pointing to a pointer to the character array

Returns

1 if a non-space character is found, 0 if the string terminates

This function advances a pointer to a string to consume as much whitespace as possible. Upon returning, *StrPos points to the first non-space character. If the string terminates without a non-space character, *StrPos is the location of the null terminator.

Here is the caller graph for this function:

int ParseNumber	(	double *	Number,
		const char **	StrPtr,
		int	FloatAllowed
	)

Read a number from a string.

Parameters

Number	is a pointer to where to store the result
StrPtr	char** pointing to a pointer to the character array
FloatAllowed	whether decimal or scientific notations are allowed

Returns

1 on success, 0 on failure

The routine consumes leading whitespace and reads as many characters as possible to form a valid floating-point number in decimal or scientific notation. Upon returning, *StrPos points to the character immediately following the number.
