BufReader¶

createInstance¶

static BufReader *createInstance(const char *pFile, uint iBufSize);

Create an instance of BufReader to read from the specified file.

pFile

Name of file to read from.

iBufSize

Size of buffer to use

createInstance¶

static BufReader *createInstance(FILE *fIn, uint iBufSize);

Create an instance of BufReader to read from the specified file.

fIn

File handle for input file.

iBufSize

Size of buffer to use

destructor¶

~BufReader();

The destructor.

getNextChar¶

char *getNextChar();

Gets the next character and moves the internal cursor by 1. If the end of the buffer has been reached, the next block is read from the file.

Returns the next character.

getBlock¶

int getBlock(char *p, uint iSize);

Reads a block of the specified size to the proveded buffer.

p

Pointer to a char array.

iSize

Number of characters to read into p

Returns 0 on success, -1 on failure.

getBlock¶

int getBlock(char *p, uint *piSize, const char *pLim);

Reads a block until the string pLim has been read, but at most the specified number of characters.

p

Pointer to a char array.

iSize

Maximum number of characters to read into p.

pLim

Limiting string.

Returns 0 on success, -1 on failure.

skip¶

char *skip(uint iSkip);

Skip ove the next iSkip characters

Returns 0 on success, -1 on error

getPos¶

long getPos();

Get current position in file.

Returns current position in file.

getCurPos¶

long getCurPos();

Get current position in buffer.

Returns current position in buffer.

loadFromCurrentPos¶

int loadFromCurrentPos();

Load the buffer from current file position.

Returns 0 on success, -1 on failure.

constructor¶

BufReader();

Initializes members.

initialize¶

int initialize(const char *pFile, uint iBufSize);

pFile

Name of the file to be read.

iBufSize

Buffer size.

Opens the file, allocates the buffer and resets members.

initialize¶

int initialize(FILE *fIn, uint iBufSize, bool bCloseFile);

fIn

File handle to opened input file.

iBufSize

Buffer size.

bCloseFile

If true BufReader will close the file at the end of its life.

Allocates the buffer and resets members.
