rfio_fopen - opens a file
#include <sys/types.h> #include "rfio_api.h" FILE *rfio_fopen (char *path, char *mode); Under Linux, for large files: #define _LARGEFILE64_SOURCE #include <sys/types.h> #include "rfio_api.h" FILE *rfio_fopen64 (char *path, char *mode); For large files, under other systems: #include <sys/types.h> #include "rfio_api.h" FILE *rfio_fopen64 (char *path, char *mode);
rfio_fopen opens the file whose name is the string pointed to by path , a character string containing the filename specification, and associates a FILE stream with it. mode is an access mode indicator. One of the characters "r" or "w". rfio_fopen64 allows to open large files (see NOTES).
This routine returns NULL if the operation failed or a non-NULL pointer to a FILE structure if the operation was successful. If it fails, serrno variable is set appropriately.
ENOENT The named file/directory does not exist or is a null pathname. EACCES Search permission is denied on a component of the path prefix. EFAULT path is NULL ENOTDIR A component of path prefix is not a directory. EINVAL The mode provided to local open is invalid (see fopen(3)) EMFILE Too many open files ECONNRESET Connection reset by peer ETIMEDOUT Connection timed out ECONNREFUSED Connection refused EHOSTUNREACH No route to host SENOSHOST Host unknown. SENOSSERV Service unknown. SEBADVERSION Version ID mismatch SECOMERR Communication error. SERTYEXHAUST Retry count exhausted SENORCODE Host did not return error number SEHOSTREFUSED Host is not on local network and no mapping found
On Irix, Tru64 and IA64 the 64 bit mode is the default one, rfio_fopen and rfio_fopen64 are identical.
