Returns the name of the symbol associated with index isym in the project hprj.
Each project has an index of symbols, sorted by symbol name. GetProjSymName maps an index to a symbol name. Symbol index values start at zero and go up to the count returned by GetProjSymCount minus one.
This example interates through all project symbols:
isymMax = GetProjSymCount (hprj)
isym = 0
while (isym < isymMax)
{
symname = GetProjSymName (hprj, isym)
..
isym = isym + 1
}
