C++ (Cpp) posix_to_semihost_open_flags Examples

Example #1

File: LocalFileSystem.cpp Project: Archcady/mbed-os

FILEHANDLE local_file_open(const char* name, int flags) {
    int openmode = posix_to_semihost_open_flags(flags);
    if (openmode == OPEN_INVALID) {
        return (FILEHANDLE)NULL;
    }

    FILEHANDLE fh = semihost_open(name, openmode);
    if (fh == -1) {
        return (FILEHANDLE)NULL;
    }

    return fh;
}

Example #2

File: LocalFileSystem.cpp Project: 0x00f/stm32

FileHandle *LocalFileSystem::open(const char* name, int flags) {
    /* reject filenames with / in them */
    for (const char *tmp = name; *tmp; tmp++) {
        if (*tmp == '/') {
            return NULL;
        }
    }

    int openmode = posix_to_semihost_open_flags(flags);
    if (openmode == OPEN_INVALID) {
        return NULL;
    }

    FILEHANDLE fh = semihost_open(name, openmode);
    if (fh == -1) {
        return NULL;
    }
    return new LocalFileHandle(fh);
}

Example #3

File: LocalFileSystem.cpp Project: Archcady/mbed-os

int LocalFileSystem::open(FileHandle **file, const char* name, int flags) {
    // No global state modified so function is thread safe

    /* reject filenames with / in them */
    for (const char *tmp = name; *tmp; tmp++) {
        if (*tmp == '/') {
            return -EINVAL;
        }
    }

    int openmode = posix_to_semihost_open_flags(flags);
    if (openmode == OPEN_INVALID) {
        return -EINVAL;
    }

    FILEHANDLE fh = semihost_open(name, openmode);
    if (fh == -1) {
        return -EIO;
    }

    *file = new LocalFileHandle(fh);
    return 0;
