◆ xmlCheckUTF8()

int xmlCheckUTF8 ( const unsigned char utf)

xmlCheckUTF8: @utf: Pointer to putative UTF-8 encoded string.

Checks @utf for being valid UTF-8. @utf is assumed to be null-terminated. This function is not super-strict, as it will allow longer UTF-8 sequences than necessary. Note that Java is capable of producing these sequences if provoked. Also note, this routine checks for the 4-byte maximum size, but does not check for 0x10ffff maximum value.

Return value: true if @utf is valid.

xmlChar * xmlStrncat ( xmlChar cur,

xmlStrncat: @cur: the original xmlChar * array @add: the xmlChar * array added @len: the length of @add

a strncat for array of xmlChar's, it will extend @cur with the len first bytes of @add. Note that if @len < 0 then this is an API error and NULL will be returned.

Returns a new xmlChar *, the original @cur is reallocated and should not be freed.
