Functions | |
| palStatus_t | pal_fsMkDir (const char *pathName) |
This function attempts to create a directory named pathName. More... | |
| palStatus_t | pal_fsRmDir (const char *pathName) |
| This function deletes a directory. More... | |
| palStatus_t | pal_fsFopen (const char *pathName, pal_fsFileMode_t mode, palFileDescriptor_t *fd) |
This function opens the file whose name is specified in the parameter pathName and associates it with a stream that can be identified in future operations by the fd pointer returned. More... | |
| palStatus_t | pal_fsFclose (palFileDescriptor_t *fd) |
| This function closes an open file object. More... | |
| palStatus_t | pal_fsFread (palFileDescriptor_t *fd, void *buffer, size_t numOfBytes, size_t *numberOfBytesRead) |
This function reads an array of bytes from the stream and stores it in the block of memory specified by buffer. The position indicator of the stream is advanced by the total amount of bytes read. More... | |
| palStatus_t | pal_fsFwrite (palFileDescriptor_t *fd, const void *buffer, size_t numOfBytes, size_t *numberOfBytesWritten) |
This function starts to write data from buffer to the file at the position pointed by the read/write pointer. More... | |
| palStatus_t | pal_fsFseek (palFileDescriptor_t *fd, int32_t offset, pal_fsOffset_t whence) |
| This function moves the file read/write pointer without any read/write operation to the file. More... | |
| palStatus_t | pal_fsFtell (palFileDescriptor_t *fd, int32_t *pos) |
| This function gets the current read/write pointer of a file. More... | |
| palStatus_t | pal_fsUnlink (const char *pathName) |
| This function deletes a single file from the file system. More... | |
| palStatus_t | pal_fsRmFiles (const char *pathName) |
| This function deletes all files and folders in a specified folder from the file system. Flat remove only. More... | |
| palStatus_t | pal_fsCpFolder (const char *pathNameSrc, char *pathNameDest) |
| This function copies all files from the source folder to the destination folder. Flat copy only. More... | |
| palStatus_t | pal_fsSetMountPoint (pal_fsStorageID_t dataID, const char *Path) |
| This function sets the mount directory for the given storage ID (primary or secondary). More... | |
| palStatus_t | pal_fsGetMountPoint (pal_fsStorageID_t dataID, size_t length, char *Path) |
| This function gets the mount directory for the given storage ID (primary or secondary). More... | |
| palStatus_t | pal_fsFormat (pal_fsStorageID_t dataID) |
| This function formats a given SD partition. More... | |
| bool | pal_fsIsPrivatePartition (pal_fsStorageID_t dataID) |
| This function will return whether a given partition is used only by PAL or not. More... | |
| void | pal_fsCleanup (void) |
| This function will perform clean up on all file system resources. More... | |
