Can someone lend some inline advice?
I have a bit of inline code I'm trying to migrate to GLBasic. The first function opens a file, creates a memory buffer and dumps the contents in the file.
I know how to read a file into a string or an array, but I'm not sure then how to modify the later functions that are written to use a C memory buffer to either use the GLBasic string or array.
The C code that opens a file and dumps the contents into a memory buffer (so you know what the variables used are) :-
FILE *fh;
if((fh = fopen(argv[1], "rb")))
{
unsigned long size;
if(!fseek(fh,0,SEEK_END) && (size = ftell(fh)) != EOF && !fseek(fh,0,SEEK_SET))
{
unsigned char *mem;
if((mem = (unsigned char *) malloc(size+3)))
{
if(fread(mem, size, 1, fh) == 1)
Here's one of the later bits code that uses the memory buffer. How would I change this (the "Mem" pointer) to access the contents of a GLBasic string or array please?
unsigned long DoCRC32_1(const unsigned char * Mem, signed long Size)
{
unsigned long val = 0;
unsigned long buf[256];
[... populates the buf array...]
while(Size--)
val = buf[*(Mem++);

You can use the buffer then as:
((const unsigned char*)buffer_Str.c_str())
Awesome! Cheers!
