Do the CCS support the file I/O access ?

Hi,
I just want to know, is it the CCS software don't support the file I/O access ? Because I have a program that worked well to access a txt file using c compiler but doesn't work when I use the CCS. Thanks.

Regards,

CCS supports file I/O. You have to include the correct header files.

Files can be on the host and your DSP program can access them over JTAG emulator.
However, CCS file I/O is very slow and you shouldn't mix that part of your DSP
program with real-time code.

How much effort / Googling are you doing on this? Shouldn't be hard. I tried:

fopen include site:ti.com

and the answer is sitting there #1 hit.

Hi,

This is the program that I run in CCS. May I know what is the header file that I should include in the program ? Thanks.

#include int main() { FILE *f; char s[1000]; f=fopen("infile","r"); if (!f) return 1; while (fgets(s,1000,f)!=NULL) printf("%s",s); fclose(f); return 0; }
