This function gets some basic statistics about the file.
- Parameters
-
fname is the name of the file r_nlines is the number of lines in the file. If it is NULL, this information is not returned. r_ntokens is the number of tokens in the file. If it is NULL, this information is not returned. r_max_nlntokens is the maximum number of tokens in any line in the file. If it is NULL this information is not returned. r_nbytes is the number of bytes in the file. If it is NULL, this information is not returned.
| intmax_t gk_getfsize | ( | char * | filename | ) |
Returns the size of the file in bytes.
This function returns the size of a file as a 64 bit integer. If there were any errors in stat'ing the file, -1 is returned.
- Note
- That due to the -1 return code, the maximum file size is limited to 63 bits (which I guess is okay for now).
