The dirent.h shipped with the risc-v compiler lacks `extern "C"`
declartion and causes linkage declartion conflict when included in C++
files. Use the dirent.h from newlib only to avoid this issue.
When base_path has len == 0, the code used to compare base_path[-1]
with '/'. Fix by correcting the length check.
Also mention the case of zero-length base_path in the API reference.
Closes https://github.com/espressif/esp-idf/issues/5514
- implemented SYS_DRVINFO syscall and version handling for the semihosting driver
- removed a support of old oocd versions
renamed kconfig options:
- CONFIG_SEMIHOSTFS_HOST_PATH_MAX_LEN to CONFIG_VFS_SEMIHOSTFS_HOST_PATH_MAX_LEN
- CONFIG_SEMIHOSTFS_MAX_MOUNT_POINTS to CONFIG_VFS_SEMIHOSTFS_MAX_MOUNT_POINTS
CONFIG_VFS_SUPPORT_IO: for basic I/O functions support
CONFIG_VFS_SUPPORT_DIR: for file/directory functions support
CONFIG_VFS_SUPPORT_SELECT: for select support
This fix is for compatibility with lwip_select(). It moves the lock to
UART which is the only VFS driver which is implemented and is not
"thread-safe".
Previously ioctl was declared as a macro in lwip/sockets.h.
Disabling LWIP_POSIX_SOCKETS_IO_NAMES removed that declaration.
This adds sys/ioctl.h file and the missing declaration.
Also adds missing includes in vfs.c.
Previously VFS driver for UART could only use simple non-blocking
functions to read from and write to the UART. UART driver provides more
complex blocking and interrupt-driven functions, which can be used
instead.
This commit adds optional support for using UART driver's functions.
Also added is a more flexible mechanism for configuring newline
conversion rules on input and output.
This commit also fixes a bug that all UARTs shared one static variable
used as a character buffer in newline conversion code. This variable is
changed to be per-UART.
- spaces->tabs in tasks.c
- update vfs_uart.c to use per-UART locks
- add license to vfs_uart.c
- allocate separate streams for stdout, stdin, stderr, so that they can be independently reassigned
- fix build system test failure
- use posix off_t instead of newlib internal _off_t
