system_fwrite

The system_fwrite function writes a specified number of bytes from a specified buffer into a specified file.

Before system_fwrite can be used, you must open the file using any of the system_fopen functions (except system_fopenRO).

Syntax

int system_fwrite(SYS_FILE fd, char *buf, int sz);

Returns

The constant IO_OKAY if the write succeeded, or the constant IO_ERROR if the write failed.

Parameters

SYS_FILE fd is the platform-independent file descriptor.

char *buf is the buffer containing the bytes to be written.

int sz is the number of bytes to write to the file.
