PCRE_FREE_STUDY(3)

πŸ’– PCRE_FREE_STUDY β€” bestie edition πŸ’–

okay so this is one of the PCRE pages, aka Perl-compatible regular expressions, from the Library Functions Manual. it's a lil guy but it's important, so let's go 🫢


✨ NAME ✨

PCRE β€” Perl-compatible regular expressions πŸ’…


🌸 SYNOPSIS 🌸

#include <pcre.h>

void pcre_free_study(pcre_extra *extra);

void pcre16_free_study(pcre16_extra *extra);

void pcre32_free_study(pcre32_extra *extra);

three whole flavours, one for each width, and they all do the same vibe πŸ¦‹


πŸŽ€ DESCRIPTION πŸŽ€

so pcre_free_study() is the cleanup crew function. you use it to free the memory that got used for the data generated by a call to pcre[16|32]_study() β€” like, once you don't need that studied data anymore, this is how you let it go 🧚✨

the argument must be the result of such a call. no cap, that's a hard requirement, not a suggestion πŸ’€

and if you want the full lore: there's a complete description of the PCRE native API over on the pcreapi page, and a description of the POSIX API on the pcreposix page. go read those when you're ready to level up πŸ‘‘


that's it, that's the whole page, short and iconic πŸ’œ this was PCRE 8.30, dated 24 June 2012, and it's the PCRE_FREE_STUDY(3) page signing off β€” mwah, take care of your memory bestie, free what you study πŸ“πŸ’–
