Top Forums Programming C: inputting string of unknown length Post 303040989 by apmcd47 on Monday 11th of November 2019 05:37:58 PM

realloc() is not guaranteed to reallocate in situ, which is why you do
Code:
str = realloc(str, mem);

rather than
Code:
realloc(str, mem);

The next_read variable should be reset with something like
Code:
next_read = str + strlen(str);

Basically you were writing into the old area of memory when str was now pointing to a new area.

NAME
findstr - find strings for inclusion in message catalogs SYNOPSIS
file ... DESCRIPTION
examines files of C source code for uncommented string constants which it places, along with the surrounding quotes, on the standard out- put, preceding each by the file name, start position, and length. This information is used by (see insertmsg(1)). does not output strings that are parameters of the routine (see catgets(3C)). EXTERNAL INFLUENCES
Environment Variables determines the interpretation of comments and string literals as single- and/or multi-byte characters. determines the language in which messages are displayed. If or is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty variable. If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See environ(5). International Code Set Support Single- and multi-byte character code sets are supported. WARNINGS
outputs initialization strings of static string variables. Calling with these strings causes their replacement with a call to (see cat- gets(3C)). Since the initializer must be a string, this assignment results in an invalid C declaration. For example, the following line: is modified by (see insertmsg(1)) to: These strings should be manually removed from output before being input to will not be provided in future HP-UX releases.
