SysReAllocStringLen

pbstr, pch, cch)
BSTR FAR* pbstr
OLECHAR FAR* pch
unsigned int cch

Creates a new BSTR containing a specified number of characters from an old BSTR and frees the old BSTR.

Parameter

pbstr

Pointer to a variable containing a BSTR.

pch

Pointer to cch characters to copy, or NULL to keep the string uninitialized.

cch

Number of characters to copy from pch*. A null character is placed afterwards, making a total of cch+1 characters allocated.

Return Value

Returns True if the string is successfully reallocated, or False if insufficient memory exists.

Comments

Allocates a new string, copies cch characters from the passed string into it, and then appends a null character. Frees the BSTR currently referenced by pbstr and resets pbstr to point to the new BSTR. If pch is NULL, a string of length cch is allocated, but not initialized.

The string pch can contain embedded null characters and need not end with a null.
