AG_FILE(3) FreeBSD Library Functions Manual AG_FILE(3) NAME AG_File -- agar file access routines SYNOPSIS #include <agar/core.h> DESCRIPTION AG_File provides a consistent interface to basic filesystem operations (which may be implemented differently under different platforms). FILES int AG_GetFileInfo(const char *path, AG_FileInfo *fileInfo) int AG_GetSystemTempDir(char *dst, size_t dstLen) int AG_FileExists(const char *path) int AG_FileDelete(const char *path) The AG_GetFileInfo() function returns information about the specified filesystem object, into the structure: typedef struct ag_file_info { enum ag_file_info_type type; int perms; int flags; } AG_FileInfo; The type field can take on the values: AG_FILE_REGULAR Regular file AG_FILE_DIRECTORY File represents a directory AG_FILE_DEVICE File is a special device AG_FILE_FIFO File a POSIX fifo AG_FILE_SYMLINK File is a symbolic link AG_FILE_SOCKET File is a Unix-domain socket The perms field can contain the following permission flags, assumed to be true under the effective privileges of the current process: AG_FILE_READABLE File may be read from AG_FILE_WRITEABLE File may be written to AG_FILE_EXECUTABLE File is executable The flags field allows the following values: AG_FILE_SUID File has setuid bit set AG_FILE_SGID File has setgid bit set AG_FILE_ARCHIVE File is marked as being an archive AG_FILE_HIDDEN File is marked as hidden AG_FILE_TEMPORARY File is marked as temporary DIRECTORIES int AG_MkDir(const char *path) int AG_MkPath(const char *path) int AG_RmDir(const char *path) int AG_ChDir(const char *path) void AG_GetCWD(char *dst, size_t dstLen) AG_Dir * AG_OpenDir(const char *path) void AG_CloseDir(AG_Dir *dir) The AG_MkDir() function creates a new directory under the specified path. The AG_MkPath() variant tries to create additional directories if ele- ments of the path are missing. Both return 0 on success, -1 on failure. AG_RmDir() removes the specified directory, assumed to be empty, return- ing 0 on success and -1 on failure. The AG_ChDir() function changes the working directory to the specified value, returning 0 on success and -1 on failure. AG_GetCWD() returns the current working directory path into dst, assumed to be dstLen bytes in size. AG_OpenDir() opens the specified directory. If successful, the function returns a newly allocated AG_Dir structure: typedef struct ag_dir { char **ents; /* Filenames */ int nents; } AG_Dir; The ents array contains the filenames for all directory entries. Regard- less of the filesystem's character encoding, ents is in UTF-8 encoding. AG_CloseDir() closes the given directory. UTILITY ROUTINES const char * AG_ShortFilename(const char *path) void AG_RegisterFileExtMappings(const AG_FileExtMapping *map, Uint count) AG_ShortFilename() returns a pointer to the first character of the last element of a pathname path. Agar maintains a general-purpose table mapping file extensions to Agar object classes. The AG_RegisterFileExtMappings() function registers a set of new file extension descriptions. The map argument should point to an array containing up to count items: typedef struct ag_file_ext_mapping { const char *ext; const char *descr; void *cls; int editDirect; } AG_FileExtMapping; The ext member should be set to the file extension, including the leading dot. descr is a short description string. The cls pointer should be set to to an Agar object class (see AG_ObjectClass(3)) with a load() function capable of loading files with the given extension. Set editDirect to 1 to advise that objects of this class may be freely created, loaded from file and directly edited with the edit function of the class.
