◆ gk_getextname()

char* gk_getextname ( char * path )

Definition at line 159 of file fs.c.

◆ gk_getfilename()

char* gk_getfilename ( char * path )

Definition at line 173 of file fs.c.

◆ gk_getfilestats()

void gk_getfilestats	(	char *	fname,
		size_t *	r_nlines,
		size_t *	r_ntokens,
		size_t *	r_max_nlntokens,
		size_t *	r_nbytes
	)

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.

Definition at line 79 of file fs.c.

◆ gk_getfsize()

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).

◆ gk_mkpath()

int gk_mkpath ( char * pathname )

Definition at line 207 of file fs.c.

◆ gk_rmpath()

int gk_rmpath ( char * pathname )

Definition at line 219 of file fs.c.
