Returns the name of the symbol indexed by isym in the buffer hbuf. Each parsed file buffer maintains an index of symbols defined in it. The index is sorted by symbol name. Symbol index values start at zero and go up to the count returned by GetBufSymCount minus one. This function maps a symbol index (isym) into a symbol name.
This example iterates through all file buffer symbols:
isymMax = GetBufSymCount (hbuf)
isym = 0
while (isym < isymMax)
{
symname = GetBufSymName (hbuf, isym)
...
isym = isym + 1
}
