Detailed Description

File functions for sds strings.

Function Documentation

sds_basename()

sds sds_basename

(

sds

s

)

Replacement for basename function. Modifies the sds string in place.

Parameters

s	sds string to apply basename function

Returns

new pointer to s

sds_basename_uri()

void sds_basename_uri

(

sds

uri

)

Calculates the basename for files and uris

• for files the path is removed
• for uris the query string and hash is removed

  Parameters

  uri	sds string to modify in place

sds_dirname()

sds sds_dirname

(

sds

s

)

Replacement for dirname function. Modifies the sds string in place.

Parameters

s	sds string to apply dirname function

Returns

new pointer to s

sds_getfile()

sds sds_getfile	(	sds	s,
		const char *	file_path,
		size_t	max,
		bool	remove_newline,
		bool	warn,
		int *	nread )

Reads a whole file in the sds string s from *fp Removes whitespace characters from start and end

Parameters

s	an already allocated sds string that should hold the file content
file_path	filename to read
max	maximum bytes to read
remove_newline	removes CR/LF if true
warn	log an error if file does not exist
nread	Number of bytes read, -1 error reading file, -2 file is too big

Returns

pointer to s

sds_getfile_from_fp()

sds sds_getfile_from_fp	(	sds	s,
		FILE *	fp,
		size_t	max,
		bool	remove_newline,
		int *	nread )

Reads a whole file in the sds string s from *fp Removes whitespace characters from start and end

Parameters

s	an already allocated sds string that should hold the file content
fp	FILE pointer to read
max	maximum bytes to read
remove_newline	removes CR/LF if true
nread	Number of bytes read, -2 if file is too big

Returns

pointer to s

sds_getline()

sds sds_getline	(	sds	s,
		FILE *	fp,
		size_t	max,
		int *	nread )

Getline function that trims whitespace characters

Parameters

s	an already allocated sds string
fp	a file descriptor to read from
max	max line length to read
nread	Number of bytes read, -1 on EOF

sds_replace_file_extension()

sds sds_replace_file_extension	(	sds	filename,
		const char *	ext )

Replaces the file extension

Parameters

filename	sds string to replace the extension
ext	new file extension

Returns

newly allocated sds string with new file extension

sds_sanitize_filename()

void sds_sanitize_filename

(

sds

filename

sds string to sanitize

sds_strip_file_extension()

void sds_strip_file_extension

(

sds

filename

)

Removes the file extension

Parameters

filename

sds string to remove the extension

sds_strip_slash()

void sds_strip_slash

(

sds

dirname

)

Strips all slashes from the end

Parameters

dirname

sds string to strip
