I have a problem that I want to insert and delete some chars in the middle of a file. fopen() and fdopen() just allow to append at the end.
Is there any simple method or existing library that allow these actions? Thanks in advance.:confused: (7 Replies)

whereis
whereis(1B) SunOS/BSD Compatibility Package Commands whereis(1B) NAME
whereis - locate the binary, source, and manual page files for a command SYNOPSIS
/usr/ucb/whereis [-bmsu] [-BMS directory... -f] filename... DESCRIPTION
The whereis utility locates source/binary and manuals sections for specified files. The supplied names are first stripped of leading path- name components and any (single) trailing extension of the form .ext, for example, .c. Prefixes of s. resulting from use of source code control are also dealt with. whereis then attempts to locate the desired program in a list of standard places: etc /sbin /usr/bin /usr/ccs/bin /usr/ccs/lib /usr/lang /usr/lbin /usr/lib /usr/sbin /usr/ucb /usr/ucblib /usr/ucbinclude /usr/games /usr/local /usr/local/bin /usr/new /usr/old /usr/hosts /usr/include /usr/etc OPTIONS
The following options are supported: -b Searches only for binaries. -B Changes or otherwise limits the places where whereis searches for binaries. -f Terminates the last directory list and signals the start of file names, and must be used when any of the -B, -M, or -S options are used. -m Searches only for manual sections. -M Changes or otherwise limits the places where whereis searches for manual sections. -s Searches only for sources. -S Changes or otherwise limit the places where whereis searches for sources. -u Searches for unusual entries. A file is said to be unusual if it does not have one entry of each requested type. Thus `whereis -m -u *' asks for those files in the current directory which have no documentation. EXAMPLES
Example 1 Finding files Find all files in /usr/bin which are not documented in /usr/share/man/man1 with source in /usr/src/cmd: example% cd /usr/ucb example% whereis -u -M /usr/share/man/man1 -S /usr/src/cmd -f * FILES
o /usr/src/* o /usr/{doc,man}/* o /etc, /usr/{lib,bin,ucb,old,new,local} ATTRIBUTES

chdir(2), attributes(5) BUGS
Since whereis uses chdir(2) to run faster, pathnames given with the -M, -S, or -B must be full; that is, they must begin with a `/'. SunOS 5.11 10 Jan 2000 whereis(1B)
