system_fopenRW

The system_fopenRW function opens the file identified by path in read-write mode and returns a valid file descriptor. If the file already exists, system_fopenRW does not truncate it. Use this function to open files that will be read from and written to by your program.

Syntax

SYS_FILE system_fopenRW(char *path);

Returns

The system-independent file descriptor (SYS_FILE) if the open succeeded, or 0 if the open failed.

Parameters

char *path is the file name.

Example

SYS_FILE fd;fd = system_fopenRO(pathname);if (fd == SYS_ERROR_FD)    break;
