Detailed Description

Expandable String Buffer.

Member Function Documentation

ytStrBuff_add()

ytStrBuff * ytStrBuff_add	(	ytStrBuff *	this,
		char	c
	)

Adds a character to the end of the buffer.

Parameters

this	pointer to the ytStrBuff instance.
c	character letter added to the ytStrBuff.

ytStrBuff_addStr()

ytStrBuff * ytStrBuff_addStr	(	ytStrBuff *	this,
		const char *	str
	)

Adds a string to the end of the buffer.

Parameters

this	pointer to the ytStrBuff instance.
str	string to be added to the ytStrBuff.

ytStrBuff_clear()

void ytStrBuff_clear

(

ytStrBuff *

this

)

Clears the buffer.

Parameters

this	pointer to the ytStrBuff.

ytStrBuff_delete()

void ytStrBuff_delete

(

void *

this

)

Deletes the ytStrBuff instance.

Parameters

this	pointer to the ytStrBuff to be deleted. The pointer has to be one returned by ytStrBuff_new().

ytStrBuff_expand()

ytStrBuff * ytStrBuff_expand	(	ytStrBuff *	this,
		size_t	length
	)

Expands the size of the allocated buffer memory.

The new buffer size will be the current size + length.

Generally this is used internally, and users do not need to use this directly.

Parameters

this	pointer to the ytStrBuff instance.
length	buffer size to be newly allocated.

Returns

this, or NULL if failed.

ytStrBuff_gen()

char * ytStrBuff_gen

(

const ytStrBuff *

this

)

Generates a new string identical to the string buffer.

Parameters

this	pointer to the ytStrBuff.

Returns

newly allocated pointer that has a string identical to this string buffer.

ytStrBuff_len()

size_t ytStrBuff_len

(

const ytStrBuff *

this

)

Returns the length of the string in the buffer.

This returns the length of the string, excluding the terminal NULL letter.

This is the same as ytStrBuff_length().

Parameters

this	pointer to the ytStrBuff instance.

Returns

length of the string in the buffer.

ytStrBuff_length()

size_t ytStrBuff_length

(

const ytStrBuff *

this

)

Returns the length of the string in the buffer.

This returns the length of the string, excluding the terminal NULL letter.

Parameters

this	pointer to the ytStrBuff instance.

Returns

length of the string in the buffer.

ytStrBuff_new()

ytStrBuff * ytStrBuff_new

(

)

Generates the new ytStrBuff instance.

Returns

pointer to the new ytStrBuff instance, or NULL if failed to allocate.

ytStrBuff_ptr()

void * ytStrBuff_ptr

(

const ytStrBuff *

this

)

Returns the pointer pointing to the current string.

If the buffer contains nothing, in other words, if no memory space is allocated for the buffer, then this returns NULL.

Parameters

this	pointer to the ytStrBuff.

ytStrBuff_str()

const char * ytStrBuff_str

(

const ytStrBuff *

this

)

Returns the pointer pointing to the current string.

If the buffer contains nothing, in other words, if no memory space is allocated for the buffer, then this returns the constant pointer to the empty string.

Parameters

this	pointer to the ytStrBuff.
