    XPCOM string functions

    XPCOM provides these low-level string functions to let you work with strings; however, it's often better to use one of the string classes rather than directly using these functions.

    NS_CStringAppendData
    The NS_CStringAppendData function appends data to the existing value of a nsACString instance. This is a low-level API.
    NS_CStringCloneData
    The NS_CStringCloneData function returns a null-terminated, heap allocated copy of the string's internal buffer.
    NS_CStringContainerFinish
    The NS_CStringContainerFinish function releases any memory allocated by a nsCStringContainer instance.
    NS_CStringContainerInit
    The NS_CStringContainerInit function initializes a nsCStringContainer instance for use as a nsACString.
    NS_CStringContainerInit2
    The NS_CStringContainerInit2 function initializes a nsCStringContainer instance for use as a nsACString.
    NS_CStringCopy
    The NS_CStringCopy function copies the value from one nsACString instance to another. This is a low-level API.
    NS_CStringCutData
    The NS_CStringCutData function removes a section of the string's internal buffer. This is a low-level API.
    NS_CStringGetData
    The NS_CStringGetData function gives the caller read access to the string's internal buffer.
    NS_CStringGetMutableData
    The NS_CStringGetMutableData function gives the caller write access to the string's internal buffer.
    NS_CStringInsertData
    The NS_CStringInsertData function appends data to the existing value of a nsACString instance. This is a low-level API.
    NS_CStringSetData
    The NS_CStringSetData function copies data into the string's internal buffer. This is a low-level API.
    NS_CStringSetDataRange
    The NS_CStringSetDataRange function copies data into a section of the string's internal buffer. This is a low-level API.
    NS_CStringToUTF16
    The NS_CStringToUTF16 function converts the value of a nsACString instance to UTF-16 and stores the result in a nsAString instance.
    NS_StringAppendData
    The NS_StringAppendData function appends data to the existing value of a nsAString instance. This is a low-level API.
    NS_StringCloneData
    The NS_StringCloneData function returns a null-terminated, heap allocated copy of the string's internal buffer.
    NS_StringContainerFinish
    The NS_StringContainerFinish function releases any memory allocated by a nsStringContainer instance. This is a low-level API.
    NS_StringContainerInit
    The NS_StringContainerInit function initializes a nsStringContainer instance for use as a nsAString. This is a low-level API.
    NS_StringCopy
    The NS_StringCopy function copies the value from one nsAString instance to another. This is a low-level API.
    NS_StringCutData
    The NS_StringCutData function removes a section of the string's internal buffer. This is a low-level API.
    NS_StringGetData
    The NS_StringGetData function gives the caller access to the string's internal buffer. This is a low-level API.
    NS_StringInsertData
    The NS_StringInsertData function appends data to the existing value of a nsACString instance. This is a low-level API.
    NS_StringSetData
    The NS_StringSetData function copies data into the string's internal buffer. This is a low-level API.
    NS_StringSetDataRange
    The NS_StringSetDataRange function copies data into a section of the string's internal buffer. This is a low-level API.
    NS_UTF16ToCString
    The NS_UTF16ToCString function converts the value of a nsAString instance from UTF-16 to the specified multi-byte encoding and stores the result in a nsACString instance.
