SYNOPSIS

#include <triostr.h>

DESCRIPTION

Function Documentation

TRIO_PUBLIC_STRING int trio_string_append	(	trio_string_t *	self,
		trio_string_t *	other
	)

Append the second string to the first.

Parameters

self	Dynamic string to be modified.
other	Dynamic string to copy from.

Returns

Boolean value indicating success or failure.

TRIO_PUBLIC_STRING int trio_string_contains	(	trio_string_t *	self,
		trio_string_t *	other
	)

Search for the first occurrence of second parameter in the first.

Parameters

self	Dynamic string to be modified.
other	Dynamic string to copy from.

Returns

Boolean value indicating success or failure.

TRIO_PUBLIC_STRING trio_string_t* trio_string_create

(

int

initial_size

)

Create a new dynamic string.

Parameters

initial_size

Initial size of the buffer.

Returns

Newly allocated dynamic string, or NULL if memory allocation failed.

TRIO_PUBLIC_STRING void trio_string_destroy

(

trio_string_t *

self

)

Deallocate the dynamic string and its contents.

Parameters

self	Dynamic string

TRIO_PUBLIC_STRING char* trio_string_extract

(

trio_string_t *

self

)

Extract the content.

Parameters

self	Dynamic String

Returns

Content of dynamic string.

The content is removed from the dynamic string. This enables destruction of the dynamic string without deallocation of the content.

TRIO_PUBLIC_STRING char* trio_string_get	(	trio_string_t *	self,
		int	offset
	)

Get a pointer to the content.

Parameters

self	Dynamic string.
offset	Offset into content.

Returns

Pointer to the content.

Offset can be zero, positive, or negative. If offset is zero, then the start of the content will be returned. If offset is positive, then a pointer to offset number of characters from the beginning of the content is returned. If offset is negative, then a pointer to offset number of characters from the ending of the string, starting at the terminating zero, is returned.

TRIO_PUBLIC_STRING void trio_xstring_set	(	trio_string_t *	self,
		char *	buffer
	)

Set the content of the dynamic string.

Parameters

self	Dynamic String
buffer	The new content.

Sets the content of the dynamic string to a copy buffer. An existing content will be deallocated first, if necessary.

Remarks

This function will make a copy of buffer. You are responsible for deallocating buffer yourself.
