Function Documentation

kzsFile* kzsFopen	(	kzString	fileName,
		kzString	mode
	)

Opens a file.

kzInt kzsFclose

(

kzsFile *

file

)

Closes a file.

kzBool kzsFeof

(

kzsFile *

file

)

Checks if the end of a file has been reached.

kzInt kzsFerror

(

kzsFile *

file

)

Checks if there is an error in a file.

kzInt kzsFseek	(	kzsFile *	file,
		kzInt	offset,
		enum KzsFileOrigin	origin
	)

Seeks to given position in a file.

kzInt kzsFtell

(

kzsFile *

file

)

Gets the current position in a file.

kzInt kzsFflush

(

kzsFile *

file

)

Flushes the stream.

Writes any unwritten data to file.

kzInt kzsFgetc

(

kzsFile *

file

)

Gets a byte from a file.

kzInt kzsFputc	(	kzInt	character,
		kzsFile *	file
	)

Writes a byte to a file.

kzUint kzsFread	(	void *	buffer,
		kzUint	elementSize,
		kzUint	elementCount,
		kzsFile *	file
	)

Reads elements from a file.

Returns the number of elements read.

kzUint kzsFwrite	(	const void *	buffer,
		kzUint	elementSize,
		kzUint	elementCount,
		kzsFile *	file
	)

Writes elements to a file.

Returns the number of elements written.

kzInt kzsFileno

(

const kzsFile *

file

)

Gets file descriptor.

kzInt kzsFileGetSize

(

kzsFile *

file

)

Get the size of a file.

Returns -1 if an error occurred.

kzInt kzsFileReadSkip	(	kzsFile *	file,
		kzUint	byteCount
	)

Skips bytes in a file.

Returns the number of bytes skipped. Returns KZS_FILE_ERROR if an error occurred. This function is intended for skipping in a file only when reading it. To skip in a writable file, use kzsFseek with KZS_FILE_ORIGIN_SEEK_CUR as origin.
