- associate a stream with a file descriptor
#include <stdio.h>FILE *fdopen(intfildes,const char *mode);
Thefdopen() function associates a stream with a file descriptorfildes.
Themode argument is a character string having one of the followingvalues:
|
The meaning of these flags is exactly as specified for thefopen(3C)function, except that modes beginning withw do not cause truncation of thefile. A trailingF character can also be included in themodeargument as described infopen(3C) to enable extended FILE facility.
The mode of the stream must be allowed by the file accessmode of the open file. The file position indicator associated with thenew stream is set to the position indicated by the file offsetassociated with the file descriptor.
Thefdopen() function preserves the offset maximum previously set for the openfile description corresponding tofildes.
The error and end-of-file indicators for the stream are cleared. Thefdopen()function may cause thest_atime field of the underlying file to bemarked for update.
Iffildes refers to a shared memory object, the result of thefdopen() function is unspecified.
Upon successful completion,fdopen() returns a pointer to a stream. Otherwise, anull pointer is returned anderrno is set to indicate the error.
Thefdopen() function may fail and not seterrno if there areno freestdio streams.
Thefdopen() function may fail if:
Thefildes argument is not a valid file descriptor.
Themode argument is not a valid mode.
{FOPEN_MAX} streams are currently open in the calling process.
{STREAM_MAX} streams are currently open in the calling process.
There is insufficient space to allocate a buffer.
A process is allowed to have at least {FOPEN_MAX}stdio streams openat a time. For 32-bit applications, however, the underlying ABIs formerly requiredthat no file descriptor used to access the file underlying astdiostream have a value greater than 255. To maintain binary compatibility with earlierSolaris releases, this limit still constrains 32-bit applications.
File descriptors are obtained from calls likeopen(2),dup(2),creat(2) orpipe(2),which open files but do not return streams. Streams are necessary inputfor almost all of the standard I/O library functions.
Seeattributes(5) for descriptions of the following attributes:
