Subject: Re: help on integer to string conversion
Prototype
Char *StrIToA (
Char *s,
Int32 i
)
Parameters
← s
Pointer to a string of size maxStrIToALen in which to store the
results.
→ i
Integer to convert.
char * size = "12";
strDisplay = StrIToA (size,display);
======================
Jim,
As the above text states, the first parameter in StrIToA is a char
pointer with at least maxStrIToALen bytes, that will receive the
converted string. The char pointer you are
passing has only 3 bytes ("12\0"). Try to create it as follows:
char size[maxStrIToALen];
If it doesn't compile, you may need to allocate the memory
dinamically:
char *size = MemPtrNew(maxStrIToALen);
Don't forget to call MemPtrFree later to free the memory.
strDisplay will only receive a pointer to the buffer, so you don't
need
to initialize it.
Try:
char *strDisplay;
instead of:
char * strDisplay = "this is a test";
