2008年9月24日 · If you can modify the string: // Note: This function returns a pointer to a substring of the original string. // If the given string was allocated dynamically, the caller must not overwrite // that pointer with the returned value, since the original pointer must be // deallocated using the same allocator with which it was allocat

2013年12月18日 · I'm after the equivalent of .NET's String.Trim in C using the win32 and standard C api (compiling with MSVC2008 so I have access to all the C++ stuff if needed, but I am just trying to trim a char*). Given that there is strchr, strtok, and all manner of other string functions, surely there should be a trim function, or one that can be repurposed...

2019年7月30日 · I am writing my own trim() in C. There is a structure which contains all string values, the structure is getting populated from the data coming from a file which contains spaces before and after the beginning of a word.

The above methods are great, but sometimes you want to use a combination of functions for what your routine considers to be whitespace. In this case, using functors to combine operations can get messy so I prefer a simple loop I can modify for the trim. Here is a slightly modified trim function copied from the C version here on SO.

2010年3月16日 · Trim a string in C I was writing the String trim method in c and this is the code I came up with. I think it does the job of eliminating leading and trailing whitespaces however, I wish the code could be cleaner.

2023年2月13日 · \$\begingroup\$ Good review, but I disagree on a specific aspect. If we pass in a pointer that isn’t properly terminated (or a null pointer), then we have violated the contract of the function - it's documented to accept a string, so it's reasonable to declare that it has undefined behaviour if passed anything else.

2014年10月23日 · For what it is worth, using strlen is much more efficient than using strtok.I did some tests (omitting the file access) using strlen, strchr, strtok, strstr, strpbrk and strcspn:
