Cygwin consists of three parts: a dynamic-link library (DLL) as an API compatibility layer in the form of a C standard library providing a substantial part of the POSIX API functionality, an extensive collection of software tools and applications that provide a Unix-like look and feel, and an MOTIF-based window manager.

NAME
nand_write_page - [REPLACEABLE] write one page SYNOPSIS
int nand_write_page(struct mtd_info * mtd, struct nand_chip * chip, uint32_t offset, int data_len, const uint8_t * buf, int oob_required, int page, int cached, int raw); ARGUMENTS
mtd MTD device structure chip NAND chip descriptor offset address offset within the page data_len length of actual data to be written buf the data to write oob_required must write chip->oob_poi to OOB page page number to write cached cached programming raw use _raw version of write_page AUTHOR
