Save system() into char[]

Hi!
I have something like this :
Code:
...
char buffer[25] = "ls -l";
system(buffer);
...

and i just want to save what i get to the terminal from ls -l into a char.
I first think of doing something like ls -l>text.txt and after opening the file in my program and fscanf(). Any faster way ?

Getting Terminal information(3) 				      BrlAPI					   Getting Terminal information(3)

NAME
Getting Terminal information - How to get information about the connected Terminal. Macros #define BRLAPI_MAXNAMELENGTH 31 Functions int BRLAPI_STDCALL brlapi_getDriverName (char *buffer, size_t size) int BRLAPI_STDCALL brlapi__getDriverName (brlapi_handle_t *handle, char *buffer, size_t size) int BRLAPI_STDCALL brlapi_getDisplaySize (unsigned int *x, unsigned int *y) int BRLAPI_STDCALL brlapi__getDisplaySize (brlapi_handle_t *handle, unsigned int *x, unsigned int *y) Detailed Description Before using Raw mode or key codes, the application should always check the type of the connected terminal, to be sure it is really the one it expects. One should also check for display size, so as to adjust further displaying on it. Macro Definition Documentation #define BRLAPI_MAXNAMELENGTH 31 Maximum name length for names embeded in BrlAPI packets, not counting any termination character Function Documentation int BRLAPI_STDCALL brlapi__getDisplaySize (brlapi_handle_t *handle, unsigned int *x, unsigned int *y) int BRLAPI_STDCALL brlapi__getDriverName (brlapi_handle_t *handle, char *buffer, size_tsize) int BRLAPI_STDCALL brlapi_getDisplaySize (unsigned int *x, unsigned int *y) Return the size of the braille display int BRLAPI_STDCALL brlapi_getDriverName (char *buffer, size_tsize) Return the complete name of the driver used by brltty This function fills its argument with the whole name of the braille terminal if available, terminated with a ''. Parameters: buffer is the buffer given by the application; size is the maximum size for the name buffer. Returns: -1 on error, or a positive value giving the size of the needed buffer, if the supplied one is to small (same as snprintf()).
