Detailed Description

struct lws_plat_file_ops - Platform-specific file operations

These provide platform-agnostic ways to deal with filesystem access in the library and in the user code.

Field Documentation

close

int(* lws_plat_file_ops::close) (struct lws *wsi, lws_filefd_type fd)

close file

open

lws_filefd_type(* lws_plat_file_ops::open) (struct lws *wsi, const char *filename, unsigned long *filelen, int flags)

Open file (always binary access if plat supports it) filelen is filled on exit to be the length of the file flags should be set to O_RDONLY or O_RDWR

read

int(* lws_plat_file_ops::read) (struct lws *wsi, lws_filefd_type fd, unsigned long *amount, unsigned char *buf, unsigned long len)

Read from file, on exit *amount is set to amount actually read

seek_cur

unsigned long(* lws_plat_file_ops::seek_cur) (struct lws *wsi, lws_filefd_type fd, long offset_from_cur_pos)

seek from current position

write

int(* lws_plat_file_ops::write) (struct lws *wsi, lws_filefd_type fd, unsigned long *amount, unsigned char *buf, unsigned long len)

Write to file, on exit *amount is set to amount actually written
