pcre2_convert_context *pcre2_convert_context_create( pcre2_general_context *gcontext);
This function is part of an experimental set of pattern conversion functions. It creates and initializes a new convert context. If its argument is NULL, malloc() is used to get the necessary memory; otherwise the memory allocation function within the general context is used. The result is NULL if the memory could not be obtained.
The pattern conversion functions are described in the pcre2convert documentation.
